Hmm, this sounds like the kind of idea that's great in theory, but flawed as hell in practice. I mean, the crime issue has already been brought up, but this sort of thing means you're a great target for the local muggers, gangs, armoured car robbing thugs, etc. You'd turn your users into the replacement for ATMs in more ways than one...<p>And that's not even getting into the issues if this system has a security flaw that criminals can exploit.<p>It's a neat idea, but perhaps an example of a service that doesn't really work out well when done in a 'peer to peer' way.
