I've thought about this too, but I'm not sure, whether it is easy to
implement. AFAIK, RM tesselates surfaces into micro-polygons (each 1
pixel in size), then performs displacement (and normal calculation) and
shading. I don't know, whether (and how) it would be possible without
tesselation.

This requires derivative information, and as I wrote, it is under
consideration. I hope to release first test version soon and most likely
it will be without derivative support, hopefully POV-Ray antialiasing
compensates it a little bit.
