Interesting thought I had a little while ago. A lot of professional 
videography is now done on consumer SLR cameras. (In particular Canons). 
I know on my Mac, I can connect my canon SLR via usb and see the "video" 
live. There has been work in creating drivers that allow that video to 
be captured and/or streamed so to use it as a webcam.
My initial research suggests there was at one stage work on a V4L driver 
for this kind of capture. When I get a bit more time I hope to research 
it a bit more and see if I can make it work. I believe the reason for 
the 12minute capture limit on the SLR's is to give the sensor a chance 
to cool down, and because you don't normally need 12minutes of 
continuous footage. (What scene is shot in one shoot longer than 12 
minutes?) Not sure if there is a 12minute limit when doing capture over usb.

I'll look into this more when I can. Would be much easier than firewire, 
and the basic SLR's are < $1000 now.
