USB Webcam for Android Download – Windows
Found this while searching, would seem to work, but has to be plugged in to the PC. If you want wireless its going to have a delay, via qik or Ustream. You could use a program like Manycam to capture the stream and use that in skype, but once again it will have a delay.... and capturing it would involve you setting it up on a PC... but you could always walk away and keep broadcasting.
Best bet would be to install the above driver and try that. I'm about to give it a go.
