I love the idea and it's definitely a planned feature for the future chat room, but in terms of the chat I want to refrain from setting up any temporary systems. Not even because of the time I'd have to stick into them, but more because I'm afraid we'll (read: I'll) get too comfortable with it and laze out on making the proper chat system. The voice chatting systems are probably a while off regardless so I'm still not entirely certain if setting up a Mumble for the time being would be a good idea.
