This is something that I would also like to see.  But this is a huge 
undertaking that will have a significant impact on the architecture of Xorg.  
There are currently some specs and other work in this area that have been 
done as part of the Oyranos project.  The lead on the Oyranos project is 
Kai-Uwe Behrmann and the project web site is http://www.oyranos.org.  This 
has been talked about at some length on the OpenICC mailing list and also at 
times on this list.  So I think your best approach to this one is to contact 
Kai-Uwe as I know he would like to have additional folks willing to work on 
this.  You should also consider joining the OpenICC email list.

I also work in the color management area and I am the project lead for the 
LProf project.  LProf is an open source ICC profile creation application.  
Developement versions of LProf now allow for hardware measurement based 
display calibration and profiling on supported systems which include X, 
Windows and OS/X.
