I think the idea of prepaying a non-refundable price, and having a much higher price at the gate is about all we as organizers can do to combat the problem. Encourage people to sign up early, and make them lose their fee if they don't show up.
I usually design my games around a 40% non-attendance rate. That seems to be about the worst case scenario, unless you end up with bad weahter for game day. If you plan for the worst case and the best, your game will not be too screwed up by people not showing up. I mean it's obvious from the existance of this thread as well as what people are saying that this isn't a NEW problem, everyone who has organized a game has seen it and so you just need to accept some amount of it and plan accordingly.
