I remember the first PBCup QeHs took part in. There were little if any problems encountered by us. We seemed to be able to pick match times that were neither too late for us, or too early for the Americans. I'm almost certain our matches started and ended up as 4v4 matches.
Too much hostility going on just because we Euro's hate Americans, and the Americans hate the Euros. Lets keep the hate, its good fun and makes intercontinental matches greater, but come just act civilised until a tournament is up and running! Then... let the hate commence
(Bad idea to get bix as the spokesman btw, hard to take him seriously at all, better any of er33t take it on themselves to update information in this thread)
At the end of the day, you can't force the organisers of a tournament to use certain servers, they really don't owe anything to anyone. Offer suggestions as to how to incorporate Euro servers, and hopefully the organisers will take it into consideration, but they can honestly tell you where to stick it tbh (in a nicer way of course, another reason to lose bix btw..)
EuroPaint is an example of Euro-only servers being used, and plenty of Americans enjoyed these competitions.
