[Openicc] Color management in gimp

Definetely not kernel level - but everything else is possible (though 
not necessarily practical).
Since there is a working group at ICC to define cross-cm, it's probably 
a good idea to collect
ideas, how it can be done for Linux and similar systems. Since Linux is 
not monolithic at all -
many different libraries and programs that don't know about each other - 
a central point
where everything is put together, would be one of  the many solutions.

Writing Pixels color-managed on the screen is already part of Gimp. For 
implementation
details, the gimp-developer mailing list is probably the better location.
A local Gimp-CMM is the right way to go until a system-wide (and 
portable - Gimp
does not only work under Linux) color management system is on the way. 
This has
limitations and cannot be as "professional" as other exisiting programs 
, but at least it's a
starting point and sufficient for the standard user.
