I just wanted to mention I beleive we have made major progress to getting multiplayer / multiplatform working! I just finished playing a short game with Linux vs Windows 7 and compared the screens for a while and everything was exatcly the same on both computers. We have borrowed some code from the SprintRTS engine to accomplish this wonderful milestone and will continue to test the solution to prove out its quality.
There is a good chance the the next release will support multi-player and multiplatform
