What about something like this?

Do you think the co. might be okay with us using this say with a room labeled "dogdotcom"? You just put in whatever handle you want then that exact roomname for "Channel" and you're in providing you have Java. My puter asked me if I wanted to allow it and I said yes and that was that. Very easy...
I'm sitting there testing stuff out right now lol.
Looks like the channel will exist as long as someone starts the room...and it goes away when the last person leaves?
