In addition for GSoC 2009 we had a project to create a GPU accelerated CM 
module for X.Org composite.  The student had it working nicely on single 
monitor systems but had issues with content that was located near the 
boundaries between monitors on multi monitor systems.  So not only is Apple 
now doing this but we have most of the code needed to do this in X.Org.  
Modern graphics hardware is now so powerful that this will work even on low 
end GPUs and older mid to high end GPUs.
