Another solution that I use, and quite enjoy is Webcam Plus.

It turns your PPC into a webcam that works over activesync, bluetooth, or wifi.
I use it with skype on my home PC if I want to show someone something in my house, I just load it up and I can even still talk to them through the phone. I just drag the phone around with me and point it at crap, much easier then dragging a desktop computer with a webcam around or even a laptop.
