Just something you may be interested in, from an aesthetics point of view:

Absolutely not.  Thousands is trivial, millions is not a problem.

I would say that if you are writing an include file with python, then all you'd
need to do is write it as an array of the centers of the spheres, and the radii.
 You may find that implementing your scene using blobs and not spheres could be
faster.

There's also the possibilities of writing your data as a df3 file and rendering
it as media, or using the df3 file to render it as an isosurface.  Just for
playing around.

But overall, what you're looking to do should even be challenging for POV-Ray to
handle and render in minutes, if not less.
