You know, chosing open-space examples are not a very good idea when you
try to short-circuit a discussion. Come with some good examples where
objects bounce, are nearby and you have approx one second lag. Then
address the issues one by one.

Yes, you can obviously cripple your design so much that you only have to
send one message every ten seconds. If that is what you want?

That really depends. Many gameplayers in the 80's were pissed off
because collision detection wasn't pixel-perfect... Again, I want
examples where players don't get annoyed.
