They provide a pretty full featured demo.  My feeling is that if after trying it, it does not float your boat, then wait for Paolo's Lux Plugin.  Lux is free!

I am off to attempt the "create your own material nodes" suggestion mentioned before....with a scene of just V4, a dynamic robe (for decency), and hair.  Seems like even with that, its a lot of nodes to remake.

Will the new plugin actually create these nodes, or is it just modifying the obj materials?  Maybe I need to go re-read...
