Multiroom solution i.e. 2 or more players streaming in sync

It would be great to use Subsonic as a multiroom solution like Sonos.
What I mean is that if you could have a setup with multiple players like in my case:
player1 (iSub on Ipod touch with dock in living room)
player2 (iSub on wifes iphone with dock in Kitchen)
player3 (laptop and speakers in conservatory)
If all players could all play the same playlist in sync so you could walk from one room to the other and have a seemless music experience.
Just an idea. Only just discovered Subsonic and loving it!
