Yes. The ASICs themselves only perform the SHA256 calculations, they do not deal with anything protocol related and as such can merged-mine exactly the same as existing GPU and FPGA implementations. In other words, merged mining is part of the protocol, ASICs just do the math.
The standard rules of merged mining still apply, of course. The alternate ...

Namecoin was the first fork from Bitcoin, and is a blockchain based peer-to-peer network which maintains a decentral ledger of registered names.
It is the convention, that when you register a Namecoin name starting with d/ that appropriate DNS resolution software would translate this information to a .bit address. E.g. d/myself would be resolved to myself....

I would recommend VirCurEx. You can use it as a wallet or trade between different currencies.

Namecoin addresses, like Bitcoin addresses, are Base58 encodings of a public key hash. The encoded data starts with a version byte, and the value of this byte affects the first characters of the result.
Namecoin addresses specifically use a version byte of 52, which dictates a certain range of initials. The prefixes you listed are simply too high - they ...

I have some idea of what Namecoin was trying to achieve, but as of yet I've never seen it actually used. Is it being used for anything of significance yet, or are there plans by anyone to do so in the short to medium term?
If a distributed, first-come-first-serve domain name system for the .bit top-level domain (TLD) is significant, then yes, it has done ...

Not really. According to the Bitcoin Wiki:
Namecoin is an alternative distributed Domain Name System (DNS) on the
basis of Bitcoin software.
In contrast to a currency, according to Wikipedia
A much more general use of the word currency is anything that is used
in any circumstances, as a medium of exchange. In this use, "currency"
is a synonym ...

The algorithm of registering .bit domain is described, for example, on dot-bit wiki.
In short:
Create new domain name with name_new command: ./namecoind name_new d/<name>
Wait 12 or more blocks
Actually register the domain with name_firstupdate, where <rand> is the second (shorter) hexadecimal string returned by name_new, and <json-value> ...

.bit domains are not recognized by ICANN, the company that runs the main internet DNS. This means that most operating systems have no support for them built-in.
So, to be able to visit .bit domains, you will have to do some configuration first. You basically need to let your computer know where to search for the IP address translation of the .bit domain, as ...

Well, the fact that it will be possible to implement features similar to Namecoin that it will become obsolete.
Bitcoin is intended as a currency and a payment system, while Namecoin is designed specifically as a DNS provider for .bit domain names.
The fact that Namecoin would be able to handle .com domain names, doesn't mean the currently employed ...

So the whole point of a name reg contract is not to send transactions, rather its sole purpose is to build up a database which other nodes can then query.
Ethereum smart contracts have immutable storage. This means that you can prove your primacy to a specific name, and other people can then reference that as part of a database.
What it comes down to is ...

First, NMC is not worthless, it have a value and is traded on bitparking ( https://exchange.bitparking.com/main ) and btc-e ( https://btc-e.com/exchange ), with decent daily trading volume; people saying nmc is worthless are just people wanting to attract you to other altchains( most of them being scams imo ) .
Second, namecoin is an opensource network, it ...

520 bytes for name_update to work

It should be twice that amount but there is some bug.
As you can read in the forum thread some planning is going on to increase it to 9kb.

The disadvantage of merged mining is the additional coin daemons you have to run in the background. They all use disk space, memory, cpu cycles and bandwidth. A more annoying issue is that most of them are no longer maintained and have bugs. You may find that they crash frequently - at least namecoind does.

First, I'd like to note that Namecoin and Bitcoin are separate - they share a lot of code, but they have different blockchains and networks.
Let me talk about the problem that Bitcoin solves: double spending. It solves this by having nodes vote with their hashpower on what they think the most accurate picture of the network is. This creates an ordered list ...

As the Namecoin.info website states, "It allows you to . . . trade and transact namecoins, the digital currency NMC." So the simple answer is that yes, Namecoin is considered a currency, among other things.
The current domain name situation is a top-down hierarchy of trust where the top folks accredit those below until you get the registrar that you pay to ...

You have enough to reserve the name (the .01 network fee) but then not enough to pay the transaction fee. If you wait a day or so for the coins to age, it might work.

Clients only need to track the currently valid information (there is an expiry date for domains, for example) and not all applications need all of the data stored in the chain. So, much like Bitcoin itself, application specific versions of the information stored in the blockchain will be used by most applications and they can use SCIP or distributed trust ...

Yes. So that the whole world can see it? Yes seems like a good idea.
The NameCoin block-chain is public, although you could encrypt it in the NameCoin chain, but why there? If you are scared to lose any privates keys you should work on your back-upping strategies, not uploading it to the public domain in the hope none will realize it is a ECDSA Bitcoin ...

The point of mining is to secure the blockchain. Before you mine, you must compose the block you are trying to find a nonce for. That block will include a transaction to pay you.
If you are merged mining Bitcoin and Namecoin, you do the following:
1) You compose the Namecoin block you are trying to find a nonce for. This includes a transaction to pay you ...

Most of what you need is explained at https://en.bitcoin.it/wiki/Merged_mining_specification
When you construct the block for the primary chain (e.g. bitcoin) you need to include a merged mining header in the generation transaction (coinbase). The format of this data is explained at the URL above under "Merged mining coinbase".
If, while hashing the ...

with p2pool at least for the coins are 'merged' mining you cannot reconfigure them to go to any other account except for the default account of that wallet. However you may be able to work around this in one of the following ways depending on your coding ability.

Watch the p2pool logs and when a block is found trigger ...

Just checked, and there is a significant lack of wallets just a few months later. The only one that seems active at all is the command-line wallet. The YouTube link below can help you identify the NMC wallet's address from the command prompt in Windows, and the other link is to the page where you can download the NMC wallet's software.
BTC-e.com doesn't ...

I would definitely recommend Vircurex. They support many different currencies, and real easy to set up.

You will need to be running the standard client with some special configuration - server=1 along with rpcuser and rpcpassword set. After that, you need to build your pool server to communicate with it through Bitcoin API and handle everything else. Last part is not too Bitcoin-specific and will consume a lot of your development time (I would know, I tried it ...

I realize that this is a very old question, but I think it makes sense to give an update nevertheless. Recently, a port of the Qt-UI for Bitcoin has been done also for Namecoin. It provides full support also for name operations and even configuring domains directly without the need to come up with the correct JSON strings.
The new Namecoin-Qt is available ...

Despite being an interesting and fun problem, it will be likely pointless, due to arbitrage.
Since there is at least an open exchange supporting each currency, and since we can safely assume there is at least one single bot or person exploiting arbitrage, you will most likely get the same value for every currency.

I'm not an expert on Namecoin, but from what I understand, Namecoin works by introducing a few new types of transactions to the Bitcoin formula used for handling domain registration. After that you just need some mechanism of extracting the domain names from the blockchain and that should be enough for Namecoin to work.
