I think you missed my idea in first post

My plan is to make network game that have never been done before. Shows exactly same on every machine, on every map part and all times, while network traffic is even less than Starcraft. Who knows playable with old 56kbit modem for that 10000 units.

In example, i create a ground defence turret that shoots all nearby hostiles. There is only 1 packet total sent between server and clients which creates it, rest (shooting, deaths) is simulated only locally and synchronized in ticks. It's mainly ticks i'm worried about and having it look smooth.
