Hi, I heard of some work being done to support automatic shaders (in private talks, not sure I'm allowed to provide further details), which transparently emulate fixed pipeline for osg, but not sure of it's state or when it will be available to public,
currently osgUtil ShaderGen is a way to start with and also osgEarth/ShaderGenerator.cpp might be of some help.
