I had a similar idea and implemented it some time back. 
Results and a patch here: 
http://www.cip.physik.uni-muenchen.de/~wwieser/render/povray/ipt-patch/

I plan to implement some progressive refinement for the mosaic 
preview when I find the time and the will...
...or is anybody else working on that?

Do you mean like the Mosaic Preview function in porvay?

Well, I was not clear here: I mean mosaic-like preview with 
progressive refinement. The refinement should be steered in 
a way that the "interesting parts" appear first. Hence, it 
would work somehow like AA: the algorithm starts with 
9 rendered pixels then decides which of the resulting rectangles 
to subdivide first, etc. In the end, the complete image is rendered 
but you should be able to see the interesting parts earlier.
