Second the paid map packs. Why divide a multiplayer community?
I dunno, but I think people should take a note from Relic's Dawn of War series on this. If you don't own Chaos Rising, you can still play Chaos Rising maps and against the Chaos Space Marines, but you cannot use that faction yourself.
Update everyone's maps, and if they want to play with the toys that come with, make them pay for those. So you can still play against people who bought the map pack, but you don't get any of the fancy weapons or toys that come with unless you chalk up the cash.
