How can I share my bitcoin wallet with my family members? Such that if my grandmother spends one btc one day, I see that reflected on my computer, etc.

This is also a great safety mechanism, in case one of our family member's hard drive crashes, the other members will still have the wallet.

If you're looking for something technically straight-forward, I suggest using an "e-wallet" and giving your partner access to the wallet account.

And here are several e-wallet's listed: https://en.bitcoin.it/wiki/Category:EWallets

  • I'm looking for a way without third party help. I just want to manipulate wallets on the different local computers. Any ideas? For instance, why does the Bitcoin software only support the creation and manipulation of a single wallet? That's a bummer. – BitcoinButter Sep 15 '12 at 17:40

    Because there's a lot of risk if a wallet.dat file is open by multiple clients... bad things could happen. There's been talk of one file being "primary" or one set of private / public keys on a system being the "primary" and propagating that out, but that's a bit advanced. Check out this answer on running multiple clients to access the same file: bitcoin.stackexchange.com/questions/490/… – Dominic Tancredi Sep 15 '12 at 18:40

Electrum is a client that uses "deterministic keys", and thus multiple installations of the same wallet seed are supported.

(The only exception is if you import keys generated externally, an Electrum wallet those transactions are exclusive to the wallet in which they are imported.)

Also, Blockchain.info/wallet has a Desktop Sync feature which will keep your Bitcoin.org client's wallet.dat in sync with your Blockchain.info/wallet, and vice-versa. That doesn't mean you still don't need to backup your wallet.dat as it may not always sync perfectly but it does give a remote way for others to access your wallet.dat
