Is there a library which provides all the same address/transaction querying information as blockchain.info, depending only on having a bitcoind synchronised database?
There are a number of queries which bitcoind cannot answer. For example, bitcoind only indexes transactions which are unspent.
I realize blockchain.info has a public API, but it isn't an option for us to use this. I doubt they'd want us to spider the entire blockchain over their API anyway.
-txindex
will make it maintain a full transaction index, but that is still only by txids, and not by address/script.
