Which framework is best for eWallet bitcoin development? What are the advantages/disadvantges of various web frameworks like Django, Ruby on Rails, Flask, etc when it comes to Bitcoin? Are some better at interfacing with the daemon than others? Do some implement security better or have holes that make them inappropriate for bitcoin development? Which is the best?
Bitcoin wallet development usually involves communicating with either bitcoind through HTTP JSON RPC, or otherwise with other Bitcoin Clients through the Bitcoin Protocol over TCP. On top of that, there are the usual requirements of authenticating users, securing data and so forth. All of those security issues are not Bitcoin specific, thus I think this question would be better asked elsewhere.
