I just got a really cool idea -

Why don't I go live this weekend via, perhaps, PCM audio at golemwire.com:10002? You could use parec and pacat and netcat to "tune in" to the port and we could have a live chat only for anyone who has the technical know-how to connect!
And maybe if you want to hide your voice - well, you get to figure that out. Pipe through espeak maybe?
