I've been playing with the WebCamera Plus software from AtekSoft, and I gotta say this is really interesting stuff.
Using it as a webcam isn't so interesting, however the fact that it connects to your PC over IP means you can put it anywhere u have reception, sort of a satellite security camera that can be viewed remotely.
Also, since it can broadcast your screen as well as the camera input, you can use it as a makeshift video-out display to a computer monitor...
Even managed to work a 2-way video conversation with someone else directly from the handset... although I'll admit not the best way to do this.
I did a write up about it here:

Let me know what u guys think... with the right imagination, who knows what other uses we can think of.
