Since we're only talking about a senor shift of one pixel, would a
little subject movement necessarily ruin your shot? I'd think in many
cases, the resulting quality wouldn't be that much different than
shooting a normal image without the resolution enhancement turned on.

I don't see a lot of point to that. The logic that combines the four original
images into a a single multi-channel image is pretty straigntforward; with the
exception of the green component, which is the sum (or average) of values from
two of the original images, each component value in the merged image is just a
copy of the value in one of the four input images (possibly offset by one pixel
horizontally and/or vertically). I consider it extremely unlikely that errors
would occur in doing this combining (and suspect there may, in fact, be custom
hardware such as a one-scanline shift register to support doing this rapidly).
If there are things moving in the image enought to screw up the blend, but for
some reason you just don't notice them.
