Real time work is generally more important to my projected needs, so 
glslang looks more attractive, inasmuch as advanced shading interests 
me at all. To speak objectively, will choosing glslang result in a 
skewing of 3DKit toward real time applications? If so, is this going to 
be an impediment to its usefulness?

Consider that in many uses of 3DKit (scientific visualization), it 
might be equally important to do fast, rough, interactive work and 
slow, detailed batch processing.

Only interactive renderers will benefit form glslang, whereas maybe 
RenderMan or another shader language might be usable for interactive 
and offline renderers.

Should not the shader language be directly driven by the choice of 
renderer? Why should 3DKit have to choose one or the other? The shaders 
have no impact on the scene graph, do they?
