How to stream bytes as fast and unreliably as possible.

My game has about 4,000 objects that need to be synchronized every frame. Each object has three ints that need to synchronize.

So thats 24kb a frame that would need to be sent. For four players. So each player would be send 24kb and downloading 72kb a frame. I know this is unrealistic.

So my solution is to have each player locally simulate the world, and then as fast as it can, but low priority, have each player synchronize to each other. So that 24 kb of synchronization might get fully...
