Just a thought - LuxBlend does have a good material editor, and it's written in Python as well. Couldn't we re-use that code? At the moment, I have my problems with the material editor. I use BB's Glossy shader a lot, and LuxBlend does not even grab the color from it. I tried to set the color in Pose2Lux, but I failed. 

Attached is an image of the Luxblend Mat Editor.
