D&D has strong wargaming roots. Have you ever played with the DM as referee, one player (or team) against another?
I've already heard of Birthright play-by-e-mail games pitting regents against one another (a la Diplomacy). Political wars of assassins could be great fun. You could also play both sides of the "reverse dungeon": goblins vs. humans.
It's probably a bit frightening for a DM to see how ruthless players can be with the same resources. Some of those killer-kobold thought experiments probably pale in comparison to what a group of players might do with hundreds of kobolds.
