Hmm. There is an idea.. How about extending IOR, which is basically a 
function of the surface itself, so that you can use patterns to create 
permutations and noise in the value? Could be an interesting effect and 
placed on a small enough scale it would possibly create such a blur 
effect. Of course I have no clue how to code such a thing myself. :( 
Sigh...
