There would have to be a way for users to withdraw directly up to the amount they put it. That way everyone is there own dead man switch. Enough with the voting stuff. Don't tell doog what to do with other peoples money.
There could also be a nlocktime transaction after each bet that is posted to each user and is only valid at some future date. I'm not sure if nlocktime is useable in 0.8.6 yet.
