I don't know, but apparently they haven't done that. It does seem
that they should be able to map the sensor to discover where dust
(dead?) spots are and correct for it on the fly. I suspect that
that would be easy or difficult depending on where in a particular
image the dust element resides.
The nth generation digital cameras will probably have solved the
problem.

Since the sensors already make up some data could not the camera
makers just put a sensor at the horizontal to the main sensor and
read where the dust is and make up new data to fill in the dust spot?

I think you're correct about Canon's strategy. The Canon cleaning
procedure is simply to raise the mirror to expose the ccd cover.
After that, you're left to your own devices. Some suggested that
canned air simply blew the particles around so they found another
place to rest or were replaced by others that you had stirred up in
the process. I know that I have a few dust artifacts in my 10D, but
I haven't tried to remove them.
