Let's go with this idea then.

There might be a need to have some objects that only work with a single 
data type, which would raise some questions.  If I wrote an object that 
only made sense for colors or texcoords then how would those be 
distinguished?

For the vertex side, it would probably be best to have predefined 
'scripts' in the form of vertex shaders.  I think it might be possible 
to create shaders in some of the high-end 3D apps like Maya now, and it 
probably won't be too long before some lower end app makes shaders 
accessible to most.  If we could figure out a way to 'compile' a patch 
into a shader then that would be pretty amazing.  I have no idea how to 
do it though.
