M8 if you are interested how multiplayer interferance should be like, then check Chivalry mod for RTW.
There you don't need almost no rules to play quality multiplayer games.

I suggest you Khelvan to contact Adherbal on this, becaus he also managed to made two different systems for units. One for SP (suites more to SP players) and another for MP players. (if my info is correct here)
