My favorite cohabitive game (in case you have not already thought about it) is hacky sack. Its the team against entropy. Not as directly parallel to diplomacy but still great game.
To be cohabitive, it would have to reckon with competition between players as well. Perhaps a player will sometimes jeopardize the session by trying to showboat, hogging the sack for themselves at the risk of losing their streak somewhere where no one else will be able to take over it? (Not really, right?)
