Ok, here's my prediction.
A chinese (most likely but it could be any eastern company) outfit opens a poker/betting site that takes credit cards etc. from anywhere including the US. The US kicks up a fuss and the chinese government tells the US to shove their laws up their arse.
Er? Haven't you been reading the law. This won't work unless the US citizen has an internationally based credit card. US financial institutions will not legally be allowed to send customer payments to gambling sites. The individual will have to open an international bank account, or find a way to transfer funds to somewhere like neteller or paypal and go from there. In which case, he could use any poker site he wanted (that allows US players)
The law also says that gambling is illegal in most states of America - still doesnt stop anyone.
Ahh, but that law is a poorly worded piece of sh*t for all intents and purposes outside of sports book betting. A poker only site has never been procecuted for breaking the law... yet. There was a lengthy article by a senator who sucessfully campaigned against the last piece of legistration they tried to get through congress who basically outlined the law as it currently stood and why it didnt apply to poker. Thats why they are rushing this new legistlation in on the back of an unrelated port security bill.
A grey area, just like cardrooms operating like gutshot in this country. It wasnt de-facto "illegal", and for individual citizens it still wont be illegal in many states. But for the operators, it will be, as this article points out. And they will face procecution if they enter the US, or have staff working within the US.
