Mike, I'm interested in more what you're doing with these paper wallets. Is the idea to let us print our own paper currency for exchange between friends and family without having to even own a client?
Yeah, that's one typical use case... there are many others, and quite honestly I expect that there will be many use cases I haven't thought of, that somebody else will.
The password aspect makes it useful for much bigger amounts. "Here Abby, here's the 165 BTC you bought from me when they were $6 that I've been holding all this time for you. Now there is a new way I can just give it to you as bills, just in case you'd like to spend a couple of them on the internet without having to ask me for them, since they're money after all. There are ten
BTC10 bills and thirteen
BTC5's. The password is (some phrase based on an inside joke). Don't worry if you lose these, because as long as you don't lose the password with them, I can always bail you out for whatever you haven't spent, since I made a copy and will remember the password too." (then shove my copy of her bills in a safe deposit box and then I can stop mentally subtracting her BTC from my own wallet balance as a liability, or worrying I'll ever lose track or ability to give her her money)
