on a related note, there is at least one Warsow map that has made it into Quake Live (Focal Point).
Damn, I miss W:ET. Best multiplayer FPS I've ever played, hands down.
There's no relation to Warsow, except couple versions back he did give us permission to include it in Warsow, but we never got around retexturing and fitting it for Warsow due lack of resources, so it ended up in QL.
