professional toon lines would be great, if they could distribute with poser 9 a shader that does the ambient lines (falloff shader) with influence of lites (directional falloff shader) as separate pass for compositing in APS.  if needed, they can ask olivier or d3d to provide updated version of their toon things.

the deal with new items like this in the past (e.g. hdri, IDL, ray-traced lites, gather, GC, tone-mapping, indirect specular et al.) is that most users will never understand them or use them, no matter how many times they're explained.  if olivier or d3d can put together something, just don't devote too much $$$ to it IMVHO, as poser has already got useable line-generating funcs. why worry if it looks like a poser toon render?  most non-artists will accept that.  they don't know the difference - they just know what they like looking at.
