Thanks ! Very interesting. If we could get this to work, I think
there would be lots of nice things one could do with it. E.g.,
use drag with a light touch to move a cursor by a fraction of
the relative distance.

Regarding uneven resistance, I also wonder how much touch screen
parameters differ among devices.
