I think telus (and almost all electronic stores) sells a Linsys wireless camera that can stream video. It's called something like Home Sitter or something? I think it costs $300 for the camera. That's a bit of money..... But the camera is wireless That would be cooooool. You could put the camera anywhere and it streams to your router and then to the net. Your computer is never involved. The only other problem is that Telus likes to bundle this camera with there service and it is pricey. If you got this wireless camera, and you have a router (may have to be Linksys?), you could then use the free dns.org services to change your ip address to a url and have a free professional web cam stream.
