I agree with Michael. It's very much possible to find a game just so long as everyone finds a time that works for them. I'm also from America (East Coast) and play a game with another American, a Canadian, and 4-5 people from Europe. We all play at 5pm GMT which for me is about noon, and is somewhere between 5-7pm for my European counterparts. It's very much possible to set up games with people from all over so long as the time is properly coordinated. I personally, am actually looking for another 4e game on the weekends and am usually pretty available available, so I'd be happy to join if you guys do end up finding a game.
