I second that vote.

As well as many different video cameras if their drivers all conform
to the same user level interface. (ioctls and frame buffer access.)

It would be nice to have a video camera driver interface that is general
enough to work with many different video cameras. That way we can reuse
the user level tools with video drivers for other cameras as well.
Does anyone know if Sun or SGI have already defined a generic set of
video camera ioctls? Maybe we can just re-implement their ioctls (if
they are sensible) and avoid re-inventing a new set.
