It sounds like GPL is being made out to be something it is not. 
Don't confuse stricter rules (e.g. Debian) with being "GPL".  We can 
all read so we can all read the GPL license.

GPL does not restrict execution of the "program".  It only enforces 
rules when copying the "program".  From my own viewpoint, if the CMM 
is accessed as a pure loadable module (not using any interfaces or 
symbols from the "program") or external program, and the CMM is not 
required for normal functioning of the "program" then the CMM does not 
require distribution according to GPL rules since it is not part of 
the "program".  Any user-provided CMM could then be used as long as it 
supports the defined interface.

It would be good to have several CMMs available under Linux which all 
offer the same loadable-module interface.
