My idea is something like this:
First it measures the camera movements, and makes a rough guess. Then a
feedback system (based on data from the image sensor) tells the
camera how
successful the first estimate was. Based on that information you will
have
data for a better calculation. (A similar technique has been used
with some
success in subwoofers in sound systems).
Yes, you can do IS that way. Or you could take lots of very short
exposures and superimpose them with appropriate shifts and rotations
in post-processing. DSLR sensors don't have "electronic shuttering"
though - they're not designed to be read out while the mechanical
shutter is open. Adding that facility would increase the sensor noise.

The sensors currently used by Pentax are capable of Elentronic
shuttering, as variations of these sensors are used in the D50 and
D70(s) both of which are hybrid shutter bodies (Mechanical+electronic).
