I am probably less technical than most of you but the upside of this technology (at the point it is real world ready) might be producing what I would call a RAW file that is RAW(ER). By that I mean the file would simply contain a wider range of scene information that could be accessed by Adobe Camera Raw or the like. For the class of photographers that have no interest in RAW the information would help the JPEG engine in the camera make a "better" informed JPEG (or whatever the standard is at that time). To me capturing more scene info is better than less assuming there are minimal penalties being paid elsewhere (file size, burst shooting etc).

As a side note, it seems to me that aperture and shutter speed would still be essential as they affect not only exposure but depth of field and subject motion. Perhaps a technique that allows proper exposure independent of fstop/shutter/ASA would allow exploration of extremely wide aperture with slow shutter but no need for ND filters.

In any event it will be interesting to see what happens.
