Hi Thomas I'm not sure if I mis-read your original message but here are some comments anyway..

Then it would be your choise to use "film" lenses or not with digital bodies. Couldn't the film be also the limiting factor (resolution wise) so in such case the digital would provide better resolution with any (good enough) lens. > > - Even if the maximum aperture is larger (say f2) in digital > > use the system could limit it to be smaller (e.g. f2.8) in > > film bodies.

What I tried to say was that perhaps there could be lenses which are designed to have aperture range f2 to f22 (or f16) in digital bodies with smaller sensors and apertures f2.8 (or f4) to f22 in film bodies, both with good quallity. In such case the design wouldn't need to be as good (and large ?, heavy and expensive) as in a case where you could use f2 with film (=large "sensor"). As we know it is the edge sharpness which becomes bad first when the lens optical speed increases. In such case the designer could improve the center sharpness (for digital) and provide good edge sharpness only with smaller apertures (for film use). Just brainstorming...
