Web engine for handling coins - multiple coins or just bitcoin

[miso]

Hello everyone. I am looking for opensource php/java/python engine + SQL-like DB (or framework) for web sites which can operate with multiple crypto currencies.
Just like currency exchange like poloniex or btc-e, except the trading functionalities and business-specific stuff.
The key feature I need is support for many coins (up to 20).
Functions:
- user balances (user balances could be linked with my app users)
- TX and address management (create new address for user, check TX confirms, ...)
- specificable *coin core deamons (localhost or remote)
Is there system like this?

As an alternative, is there similar Bitcoin-only web engine in active development (and good code quality)?
I am looking for something similar to deprecated (and soon removed) account functions in bitcoind, but in form of web framework or big library which uses directly bitcoind or own SQL-like database.

Thank you for suggestions.

I found something that might be helpful to you, though it is not a finished project and there seem to be some issues.

First check out this reddit thread:

Sorry if this wasn't what you were looking for.
