Hi,

I put some more info on webcamd here:

http://www.selasky.org/hans_petter/video4bsd/

Yes, it provides a /dev/video0 that responds to V4L IOCTLs.

The only thing I noticed is that the wrong IOCTL's are coming in, and that 
they are not being translated by the linux_ioctl.c, probably because the wrong 
syscall is being used?
