   It would appear that Barbieri see themselves as a pure manufacturer of
   hardware -not software- and would like to set open interface
   specifications and export measurements a L*a*b* values, but
   unfortunately some of their "firmware" runs on the host platform and
   they cannot expose the source to this code  for a reason which I
   haven't been told.

And this raises another issue -- what if I see another use for the
device?
