I like the idea of a pass phrase based wallet, which would attract Nxt users to BTCD and vice versa.
Would the wallet work deterministically using the pass phrase? So if my computer went on fire I could log in on a brand new PC with just a pass phrase and my BTCD would be there? If so, how would this affect the current wallet.dat system? Will we have to generate a new account and send our BTCD to it?
Native ramchains will allow us to have both a localhost-client and a lite-wallet version. So, yes the goal is to get to pass-phrase type system where wallets can be accessed on multiple devices. The specifics still need to be worked out, but now with btcddev making good progress on native ramchain implementation and Onsightit getting started on the back-end, the solutions should soon become clear.
