just a quick comment to say that i don't care how long Lux takes to render now, i'd still be interested.  for me, it's not about how it can do the same thing as Poser, it's about how it can do what Poser can't.   also, it's only in version 0.7, but seems to have pretty active development. 

and if this lays the ground work for exporters to other renderers, i'll be even happier.
