So by your definition, these are not "real scenes":

And I have yet to actually see measurements of identical triangle mesh
scenes rendered significantly faster in lightflow than in povray.

I guess he was referring to another market. BTW who cares whether Lightflow
is faster than POV-Ray or not?

Agh! What text? I don't have access to the source and even if I did I
wouldn't know what to look for...

The text on the about box. It was hard to find for me too, initially.

Please explain how to do dynamically-loaded shaders using VMS. I
occasionally use my school's server to do renderings, and I don't want to
spend 15-20 minutes recompiling POV-Ray every time I want to use a new
shader.

Yep. I like. Real-time ray-tracing, right there in POV-Ray.

I like (IIRC by Chris Huff at p.u.p) proposition to add method Tesselate to
general objects method. Then there could be one general tesselation routine and
some specialized for simplest primitives.

Please create 1.000.000 spheres as separated meshes (not clone or another
referrence) and tell us memory size of it.

Touch late for that :)
