http://www.tcelectronic.com/Default.asp?Id=3789this comes close to my idea of the ultimate processor:
it would have one knob, and all the way to the right would be marked "best".
and then you just turn the knob all the way to the right to get the best sound.
this one has a couple of secondary knobs on it, which makes it not quite the ultimate plugin. but it's intriguing anyway.
just figured i'd put out the 411 on it since it looks like an interesting processing concept. i only looked at it quickly, but it looks like a combination of a dynamics processor and an eq with adaptive properties based on constantly evaluating the source material over time.
