I could take the client I developed for Artemis and split that into a stand alone program if someone else wanted to host it. I could even include some sort of TRC function. Maybe.
It wouldn't be hard to do...
1) auto-subscribe people to the Artemis channel
2) transmit everything from your main 'room' to Artemis' channel
3) transmit everything from Artemis' channel back to the main 'room'
