Would anyone apart from SharkD and myself like to see subdivision 
surfaces added to 3.7? POV-Sub's implementation* was perfect and easy to 
use. I replied to SharkD's feature request over at bugs.povray.org and 
listed some reasons explaining the benefits of this feature:

I certainly would.  I used to use PovSub before 3.7, changing primarily because
of SMP and the radiosity improvements.  I tend to use Wings3D a lot, so
subdivision is very handy for controlling the level of detail between renders
without having several copies of the same model.

who wouldn't like subsurfs in povray -- aside from isosurface and CSG nuts, that
is?  Smaller mesh files, less hassle for exporters... I vote for it, sure.
Specially as pov-sub license make the expansion readily available to the
official pov-ray code.

While I do agree that it seems to be an interesting feature, I don't 
think that it can be considered just a very small change; plus, the 
author's copyright statement seems to be problematic regarding the 
current plans to move POV-Ray to a GPL licensing scheme.

All in all I don't see it making its way into the 3.7 release. Some 
later version... maybe.

Perhaps I will contact the authors about updating the patch for 3.7. Do 
you foresee any major code changes which would keep the patch from 
working with future versions? Could work start with the POV's source as 
it is now? Of course the authors might not want to update their code, 
but I can hope :)

 From what I've seen, I guess it should fit quite snugly into 3.7 as 
well - with some minor changes of course.

That would be great! The current  Blender exporter crashes over two subdivisions
of a
rather simple mesh... :(

In fact this has been solved in more recent builds!
now I can export my 5 times subdivided meshes or any modifier and Diffuse,
alpha, specular, bump texture from blender!
