I've been experimenting with Skype, software that let's you make phone calls over the net. Quite impressive and completely free (for the time being). I've had several chats with Tony in Australia without any call charges. The sound quality is remarkable, much better than a regular phone call. I do find that it does that thing where it seems to cut the other person's voice off when I talk, but they may be because I'm using Windows ME and they say it's not really designed for that.

Anyhow, for those who want to play and have installed Skype...
(You must have Skype installed for this to work)
