I would be your best contact point for it probably. I admit I am not
really fond of the idea - keeping the webcam on and busy all of the
time to make it act like an (inaccurate) light sensor is quite a waste
of resources to me, and most laptop users would rather live without
auto-adjustment than with 1 hour less of battery. A proposal about
integrating light sensors (and maybe more hw capabilities) would be
instead much more interesting from my POV.
