Sounds like a lot of fun, if you can get the logistics and such sorted out. As for the "DM at start/stop line" problem, what about letting people do it on whatever server they want? they have to have videoproof anyway, and it would solve a whole host of problems. Also, maybe choose something else than the airfields as the gathering spots? those places are already deathtraps, and thats without a big event going down. Anyway, i'm all for this idea!
