Fencer: I agree with the others here; I don't think that there needs to be an upper limit on games played at the same time for everyone.

More sensible would be to find a way to clip the wings of those who fly too high and get into too many time forfeits as a result.

I like pedestrian's basic idea of somehow forcing people to prove they can handle lots of games before allowing them the ability to play a huge amount of games.

I also still like my notion that if you time out too many times then your tournament privileges are revoked until you have more vacation time available. With any luck the threat of the penalty would be enough to stop the problem before it even starts.
