Forget the Vienna Sausages (great post, though!) - just have every site use "play money", and have other completely unaffiliated sites (wink, wink) that buy your play money from you for cash. The problems with this are: a) does this really get around the law?, and b) will very many fish want to jump through all those hoops?. I'd say the answers are probably yes and probably no.
