I'm unclear as to why this is a problem/objection.

napolitana replicates margharita with a topping of 'anchovies' - I still like
both ;)

  Because there's no challenge. It's boring.

Apart from what you already mentioned i think there are the following 
important differences to the IRTC:

- the source code has to be provided
- manipulations in a paint program are not possible
- the images used for voting are guaranteed to be of comparable 
technical quality
- the competition is restricted to POV-Ray

While the last point is surely a questionable advantage the other ones 
make it quite different from the IRTC and could make it a great 
demonstration of the capabilities of POV-Ray.

Granted, this is very different in terms of a challenge from SSC3.
And it is similar to IRTC, on the other hand it is a short time
contest with significant public appeal and plenty of scope for 
stimulating images.

  Since when this has been allowed in the IRTC?

I have not said anything about this being allowed - i was just talking 
about the possibility.  In fact this rule has been interpreted quite 
loosely recently in the IRTC - all kind of convolution filters are 
considered not breaking the rules as well as resizing from a larger 
render.  If you remove artefacts or do other tweaks in a larger render 
and then scale it this is next to impossible to spot in the resulting image.

  I once complained about the IRTC allowing image rescaling as a
post-processing step using an image manipulation program because you
can, among other things, get a much better antialiasing than the
renderer might be able to do normally (thus the antialiasing quality
seen in the image does not correspond to the quality of the output of
the renderer).
  I was more or less astonished when the attitude of the IRTC maintainers
was that this is not only ok, but they talked in a way that they might
even want to allow even more post-processing.

  If they allow post-processing then it's not a rendering competition
anymore. It's a computer graphics competition.
  I don't think that was the original goal of the IRTC.

Then don't participate. I won't because I'm not that talented.

Wow, nice images. Immediately I want to see them in stereo.
I'm sure you've done that. Are you willing to share some
POV SDL? I wouldn't use it in competition, just to accelerate
my learning.

  I might not, because I'm not artistically very talented, and I really
lack any good ideas for this topic.
