All the payments show up in the public twitter stream, so you know how much people theoretically have at any given time. The daily max is circumvented with sockpuppets.

It doesn't have to be lucrative for someone to try it, or for it to ruin the whole idea.

Other ways to ruin things: having trouble understanding the credit crisis? Create your own with twitpay. Just start twitpaying your friends and sockpuppet accounts in crazy, interlocking ways, but way underfund your accounts, then have everyone start making claims. Who gets paid!? I don't know! It's twitterific!
