It's definitely doable. There are a number of full-duplex Java-based voice chat applications out there, maybe even some freeware ones. If Ron's interested, I could help set one up. VoIP is kinda bandwidth-intensive, though. I don't know what kind usage the server gets, but it might be too much to bother with. Bandwidth overages can get expensive. Might be better to set up a voice chat room on Yahoo! or something similar. I'll look into some options we might explore.
