Due to the VERY active community - including capable modders - I would assume that at some point in a not too far away future, there might/will be a possibility to play this also in multiplay. Perhaps not on a www.-server, but at least as a LAN game.
THY for your answer. Sounds like they "pushed" it in the end a bit too much to be the "first" to release. Well, then wait for the comming bugfixes and ... what their modding community will do to it
