Sure.  Not a problem.  I've had only real helping hand, and his camera
is broken (or was..).  Sunday night I plan to release another version
of the driver, and hope to have some sample apps with it..  (ie, xqcam
now runs using the kernel driver I've developed.  Runs nice and smooth,
with no real flashing or changes..)

The biggest problem I can see with a kernel based driver, is how to
detect when the camera has messed up without hanging the kernel or slowing
down the read loops.

Basic screen grabbing, with raw output.  Let the programs handle the rest.
The only other things I can think of are sync commands, so multiple readers
can be setup and locked-stepped on the frames, and ioctls to allow
setup of the brightness, contrast and whitebalance.
