NURBS are nothing without a good modeler.  It would be fairly easy to modify
the current Bezier code to handle simple NURBS surfaces... or at least
non-trimmed NURBS.  Trimmed NURBS are quite difficult, IMHO.  It all boils down
to tesselating the surface into an internal triangle representation.

However, modelers can already do the tesselation easily.  I've been working on
a compact mesh syntax with Thomas Baier for 3DS-to-POV conversions that would
also work to greatly reduce the size of any triangle mesh POV file.
