Doesn't windows use SxS to provide multiple versions of some dlls? I know its not for exacly the same purpose but perhaps coupled with some sort of app compat wizard we could really set hard version targets... but ofcourse it would mean building many dlls more than once

With the approach I described above (wrapper dlls) you would compile the code once and only a number of wrapper dlls that forward the exports would be linked several times. It also saves disk space.
