First of all, don't bump your own threads after a few hours, if people don't answer it's because they're not really interrested. Just a piece of advice.
AS for the OP
I think it's a great idea, though i'm not planning on using it myself, since i can't really afford to loose my money.
More thoughts on gaming for money.
E-sports (yes tournament level competitive gaming is a sport now... we're gonna be jocks) are getting bigger every day, and I think it's only natural for the betting to follow. So just like you can place your bets on your favourite soccer team or the most brutal boxer, you'll be able to place bets on the most 1337 gamers.
Another option would be like the one this post is about, though as far as i can see, they've made the game as well (correct me if i'm wrong, only looked over it briefly) What i would like to see is a service that offers some soret of support for playing for money in a lot of already existing games. So they would act as the middle man sortof like this.
Clan PWN-master and clan 1337-d00d are flaming each other on the forums and one asks the other to put his money where his mouth is. the other accept.
They go to the site gaming4keeps (made up, not real) and both transfer the bet to the site who acts as a middle man and holds them, then when the match is over the site pays the money to the winner.
The site should be able to support and manage money from clans/teams as well, so everyone could get/pay their part.
They could have refferees who join the match as spectators to avoid situations where both sides claim that they won.
They could prolly find other ways to make it interresting, like first person to get a kill-streak of (insert appropriate number here) gets a bunos or something.
They would either cherge directly for the service or make money off of advertizing.
Seeing how i actually like this idea, i bet it's already been done, but i'm too lazy to search for it.
