Excellent summary which covers the situation for native apps.

I wonder if the case is a bit different for skype and linux binaries
in general, as they run under linux emulation so perhaps the
it is the linuxulator that has to emulate the v4l(2?) calls,
and i have no idea if this needs to be done in the kernel or we
can deal with this in some libc wrapper ?
