I'm working on a dedicated server for foobillard.
Basically it works, the client side is not very userfriendly yet and there are a few known bugs.
The server can handle tournaments, it as odbc backend. Spectator mode is planned.
I'll soon release a patch for version 3.0a, hope it's not a dead idea:)
I posted the patch.
