  Hmmmm... I'm not that sure. You mean perhaps that it is much more easy to 
setup and (somewhat) faster. But I tried both methods and can't still 
decide wich one produces "more realistic" results. 

  Rafal aproach is not that bad, but I found that it works better with 
focal_blur than with aa. I also prefer the cells patern for this technique, 
as it seems to give the most smooth results.  Here is a sample with 192 
blur_samples (damn slow):

  and the same scene without "micro-normals":
