user6606: 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.

user29487: You should take a look at Abe:
Abe: a free block chain browser for Bitcoin-based currencies.
Abe reads the Bitcoin block file, transforms and loads the data into a database, and presents a web interface similar to Bitcoin Block Explorer or Blockchain.io.
Not to mention it was written in Python.
