No news on this so far.
You know, what if we did what Sauerbraten does for multiplayer. We have our games hosted locally to reduce lag (never realized it until I read about it), but can choose from a list of games to join. I'm not sure how Sauerbraten works, but the multiplayer is quite nice. Of course, we still have a problem about the lack of many players (whenever I try to play, there's nobody to play with!)
Also, how would local games over a router work with that?
Anyway, there's no work as far as I know on that, but that can be a future possibility...
