Personally, I like the idea of some hardcore CM's running an 8 hour event "live", i.e. posting missions for the entire event, so that no preplanning is needed on part of individual flyers.
The CM cadre can be the command staff for each side, with a couple working as neutral referees. Each side, of course, would have a plan, and implement it by way of the mission planner. Pilots sign on and fly, leaving the big picture to post-event analysis and the side CO's.
The pilots would only have to be flexible as to the aircraft and mission they fly.
