Actually, it has worldwide implications. The US government can seize domains registered with a US registrar, which is a fuck ton of them. emuparadise.org and epforums.org at one point (and this may still be the case, MasJ would know) we're registered with godaddy.com, a US registrar.
Fulltiltpoker, ultimatebet, and a bunch of other poker sites recently got their domains seized recently as they were registered with US registrars, and as such, had to comply with US laws and regulations, which forbid online gambling.
