Well, I see the ink limitation and linearization stuff as writing
settings files. Indeed this is the purpose because "normal" users of a
given printer and media should be able to just grab the settings and
go, maybe if necessary profile with them or relinearize to them.
As the linearisation bits just require you to read files produced by a
spectro, and write some settings files they might be written in Java,
or run like the CUPS stuff inside a Browser ...
In particular, one could very well write this in Squeak which can run
on practically any system including inside a browser.
The spectro interface itself one would not need to write because one
could parse a CGATS file, and various utilities can drive the
instruments - every instrument maker supplies a free utility, I
believe.

QTR has a moderately user-friendly way to linearize but its grayscale
only.
It can use any measuring device but I use an Eye-One.
Just a very low-level raw version of an old gimp-print is used. None
of the
color code or any of the fancy stuff in Gutenprint is used.
One of the difficulties in a nice GUI from my point of view is
portability --
OSX, Windows, Linux.
