XBox Live Texas Hold 'Em!

Ha, downloaded Texas Hold'em for XBox Live yesterday and was up 760 bucks after 2 hours of play. Nice little game, I think to be my favorite for the next couple weeks, at least until I lose all my money.
From Joystiq.com:

Not only is 'Texas Hold 'em' free to all gamers (for the first 48 hours), this title comes equipped with features that can only be found on Xbox 360. Designed to simulate the risk-reward of real poker gameplay, keep gamers honest, and discourage opponents from betting too recklessly, 'Texas Hold 'em' has an innovative new feature called Persistent Bankroll. Your virtual bankroll is tied to your Xbox Live Gamertag and keeps a running tally of your chip count. If you lose all of your chips in a poker game, you'll have to play lower stakes buy-in games to make back your stack and earn your way to the big tables.
'Texas Hold 'em' also offers multiplayer support for up to eight gamers, three modes of gameplay (Standard Games, Scenarios and Tournaments), Achievements, extensive online leaderboards and statistics, and high-definition graphics. Enjoy poker night every night with friends, family and gamers around the world...

Although, it does bring up the issue of just exactly how is the bankroll connected to my XBox live account? I have a bankroll, and I have gamerpoints in my account, 25 bucks for 2000 points. But I don't know how they're connected, yet.
