@CliffordM, I don't know Python, but implementing the game as an SSH shell would be cool indeed. However, don't forget the client needs to send and receive BTC transactions, so a standard shell client wouldn't do it.
@all, I was thinking that in terms of values, the transactions would be really small, so they would probably need a fee to be accepted in the blockchain (I'm still a newbie here; I do but best to understand how BTC works, but I'm sure I'll say a lot of shit for a while, please be patient

).
Also, they wouldn't really happen in real-time (there's always a delay of at most 10 mins for a transfer to succeed, right?), which would suck. So I guess we would need to use virtual BTC in-game and make transactions in batches from time to time. Am I right?
