webcams for X


I'm moving away from the folks soon, and we were hoping to do some kind of webcam thing. The problem is, they've got a Gateway computer and Windows 2000. I'm on an iBook with 10.1. They already have a Logitech webcam, but I don't have anything yet. Is there a way to do a video conference thing?

I looked for an MS NetMeeting for Mac but I didn't find anything. Is there anything like this that I could use and do I need a specific type of webcam?
