Alright, I have a few questions.

1. I am going to use tokamak for my game, will tokamak be compatible with your method?

2. If I were to code the server so that it had one physics simulation that either updated with the clients with the incoming data, or just extrapolated them with the old data. If each client had control of his own object. What would be the major issues I would need to deal with. I'm just trying to get an idea of how this all works...
