Yeah but you are talking about two different things.

What you want (or is more along the lines) is something like the modern day
surround sound receivers where they come with a microphone and some kind of
software in the receiver.

After you install the receiver and hook the speakers up, you plug the mic in
and place it where you usually will be sitting. Then when the receiver is in
the setup mode, it plays different white noise, sweep tones, shifting around
speaker to speaker. Then when it has all the info from the mic, it can set
the EQ and volume levels per channel by itself.

Probably not all that accurate (although the one in my Yamaha did say one
speaker was out-of-phase, and it was internally) but better than having
nothing.

To make the tv generate patterns or color sweeps is probably trivial and
cheap, but what would you use for a camera to feed back to itself? You can't
exactly include a $1000 hd camera with a $400 tv but the idea would be the
same, point the camera at the screen from where you normally sit, let the tv
run the tests, the camera feeds back to the tv and let it adjust itself to
room settings.

It may not even has to be a camera in the conventional sense, just some kind
of optical sensor that can detect white/black and color intensity or
something. As long it know what to expect from the tv (and when), it
probably would come closer than playing around with the menus manually.

Just saying it would have to be more along this line than anything like VIR
being added in.
