Stephen, You need some kind of shader composition. Personally, I prefer the VirtualProgram approach taken in the osgvirtualprogram example. IIRC, Robert did not consider this flexible enough to be a general-purpose shader comp solution, so it's not in the core OSG. However it suited our needs quite well so we adopted and extended it for use in the osgEarth project.
