TheN set up a Mumble server at mumble.madhouselive.com. Seems like Mumble is better than a voice bridge, but you'll probably hate that if you hate Skype. What's wrong with Skype? It's the same as dialing a phone, only better sound quality and you can send each other links and video chat if you want. If someone has Skype-in, you can dial in with your phone and just pretend it's a bridge. And there is no flooding or toners on Skype. And you could be messaged about the conference in progress ON SKYPE! I don't know how intellectual conversation with a bunch of weird pranksters is going to get though.
