as I said, it is always a good thing to have some working code. We'll
want to include some sort of color management with Gimp-2.0.

Read the code. I'm sorry, but AFAIK that's the only source of information 
so far. There are two modules implemented in the current developers 
version (CVS or 1.1.21). Have a look at

	modules/cdisplay_gamma.c
	modules/cdisplay_highcontrast.c

You could store that information using parasites. That would easily 
allow to have different plug-ins share the same profile data.

It wasn't my intention to discourage you. It's nice to see that someone
starts to take color managment for GIMP serious.
