Yes, an idea was to calculate few pixels, that could serve both as
predicting the rendering time of the scene, and as certificate for
correctness of the computations. 
BTW I have one question about the way you distribute the rendering on
your different PCs. How does the distribution handles the various
frequency of the processors. I mean how the load is distributed to the
processors, statically or dynimically ?
