Quote - This may seem silly, but why not use LuxRender as the previewer?  I know it can be done, as another product does just this for their preview. 

 

For me, it would seem to be beneficial to be able to see exactly what the material would look like in Luxrender.

Not silly at all - it's exactly what has been planned all along! I am, however, open to all ideas at this stage.

I need to see how feasible that approach is these days those as the Python interface to the required functionality uses Python 3, and Poser is still using Python 2.x. There is a Python 2.x compatible interface available but I don't know how well maintained it is.
