I am loosing interest in arguing here: As long as i have anything to say 
there will be no feature added to POV-Ray or MegaPOV that adds support 
for displacement mapping specifically to bicubic patches.  A generic 
mesh displacement might be interesting but redundant to some extent.

At the risk of repeating myself:  POV-Ray supports NURBS and 
displacement mapping as much as (and more than as far as isosurfaces are 
concerned) most other *renderers* available that use the raytracing 
algorithm.
