Hmm, this sounds like the kind of idea that&#x27;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&#x27;re a great target for the local muggers, gangs, armoured car robbing thugs, etc.  You&#x27;d turn your users into the replacement for ATMs in more ways than one...<p>And that&#x27;s not even getting into the issues if this system has a security flaw that criminals can exploit.<p>It&#x27;s a neat idea, but perhaps an example of a service that doesn&#x27;t really work out well when done in a &#x27;peer to peer&#x27; way.
