I think I agree with both of you :-)

On the one hand, Yet Another Standard is probably a bad idea.
Whatever we come up with should be relatively compatible with V4L.

On the other hand, improvements are not a bad idea; ideally they
should be of a form that the V4L people would be prepared to take on
board.

The real issue, though, is: who is going to do this work?  I only have
limited time, and I haven't seen much activity from others in this
area.  Given that, we shouldn't try to reinvent the wheel.
