By the way, learn about double spending, before someone runs off with your entire wallet. I bet you haven't modified bitcoin.conf to prevent trivial double spending attacks. There's a reason why the biggest bitcoin gambling game now pretty much requires 1 confirms, and it is for a good reason - because you'd be losing money otherwise when you get large enough.
