This is awesome. I just wish it was a hosted service. Somewhat regularly I want to do an online group chat with some people, and there's no good way to do it. Yeah, you could spend hours trying to get Skype installed on everyone's machine, or teach people how to use IRC (yeah right). But with a nice hosted chat service, I could just click a button, and send everyone a URL and be done with it.
I'm surprised no one has gone after this use case. I would even potentially pay a couple bucks for a "day pass" or whatever. Convore could've gone in this direction, but their signup process is too onerous. I don't want to have to walk five people in my family through signing up for their service just to get a chat going.
