I see your point here, but alas, I do not know any tuto on How to make your own shader. I think I will have a look at the 3Delight homepage, maybe there are more infos about it. I guess you have to learn to programm the shaders with the SDK.

But there are lately a couple of D|S only products which use the material or light shaders of a third person, Stonemason uses pwSurfaces on his products, Antfarm (i think it's him) uses the Pointlight shader for the Denizen ...

To me its alright, it's the final quality that counts!
