I tried a different approach to blurred reflection. Didn't work extremely
well (which isn't a surprise knowing the algorithm...). Sorry for the PNG,
but I didn't want JPG artifacts to destroy anything, and it isn't that big.

  Now you can start guessing how I did it. As you can see, I did not use
antialiasing (I deliberately rendered the image without antialiasing to show
that I did not use the antialiasing trick). And yes, I rendered it completely
with POV-Ray 3.5beta in one run (ie, I did not use any external programs, just
POV-Ray and one single .pov file).
  You can also watch for what is wrong in the reflection... Something that
just cannot be corrected with this technique :)

I think the shadows in the reflection are wrong.

  No, not really. (I mean that they aren't any wronger than anything else.)

A reflective sphere inside a slightly larger transparent sphere filled with
scattering media?

a clever setup of flat and spherical mirrors and using focal blurr?

The reflection geometry looks a bit wrong, i would say an image map
applied to the sphere...

  Nope, nothing like that.

  You are getting a bit closer, but not quite.
