Ok. here's the finished render.  Setting up the VSS props and synchronizing took just under 15 min.  I used an IBL and Infinite light for the lighting.  Render time was 7 min. I´m well happy ;)

One word about the result.  Some might say that it doesn't look like a toon render (and I might agree) but that would be missing the point.  The point is that I changed hundreds of materials in under 15 min.  I could have put a HSV node in the VSS prop for the scene so the everything but the character was in black and white.  Someone with more experience in toon setup could probably get a much more toony result.
