Presumably the existing CMM APIs used under Windows or Mac can be used 
as a design template?  Unfortunately, there are tradeoffs between 
interface abstraction and performance.  The more abstract the 
interface is, the lower the performance is likely to be unless great 
care is taken.  It seems that OpenGL performs well and has many 
similar interfacing requirements so it does seem that a good portable 
CMM pluggable-module interface can be developed without sacrificing 
too much performance.
