   Only a very small number of users will have the expertise and
   patience to manually adjust calibration curves. By all means
   provide a mechanism to supply calibration curve files along with
   ICC profiles, but widespread use of non-manufacturer supplied
   calibration, will depend on user accessible tools to generate the
   calibration curves programmatically with some sort of instrument
   (be it a spectrometer, densitometer, or scanner.)

In the case of Gutenprint, there are two "manufacturers" -- the
multinational corporations that build the hardware, and the handful of
folks exiled into their basements to hack on this stuff out of site of
their more respectable family members :-)  Sometimes we get
adjustments contributed back by our users.
