A few days ago I was watching a VOD from QuakeCon 08, namely the dm13 game between griffin and zero4. As I watched the game, I recognized the design which was very similar to nodm9 of Q3 CPMA.

I think it would be nice to have the option of playing with both nodm9 and the regular version. Maybe id could re-implement it and change a few textures?
