That text seems to cover two quite different things:

1) rendering at large sizes without the problem of the whole render
fitting in memory - this is possible with POV-Ray from the beginning on.

2) rendering scenes with high numbers of polygons.  The author of that
text seems quite enthusiastic about his ability to do so but does not
explain how his technique works.  It is almost certainly a technique only
keeping a part of the polygons in RAM and having the rest on the disc. 
Depending on how efficient this is handled (and how 'local' the rendered
scene is) this can be quite slow (interestingly the render speed is not
mentioned in that part...) The idea of displacement mapping and dynamic
subdivision has already been discussed in a different thread.  This is not
(yet) possible with POV-Ray although as a 'compensation' it supports
direct rendering of isosurfaces which is quite unique among available
renderers.
