I was thinking about your decision to maybe release the live chat rooms you have here as a plugin but what I think would be an awesome implementation of them would be a sidebar widget with a live chat in it for site support. Just incase something is needed to be brought to an admins attention then someone could type it into the live chat.
Dunno if it would be able to be site wide on everypage and synced so that it remains live whilst browsing but thought it would be a great plugin.
I have seen shoutboxes but there aren't any good looking ones out there from what I have seen and they don't integrate with a BP login.
Any feedback would be appreciated.
