It works!

Finally a way to use the iPhone as a webcam. Setup is very easy and it just works. It connects using Bonjour, so theres no hassle with IP addresses whatsoever.
The framerate on highest resolution is very low, though, but what can you expect from a standard WiFi?

I would like to see the possibility to connect via USB, too. That would also give a better framerate, I guess.
