Re-implementing surface-variable ior using old code would be 
unlikely...I'd do it by allowing a function to be specified for the ior 
value, and some sampling parameters that would allow it to just be 
perturbed at the surface or actually sampled through space, just for 
when computers eventually get fast enough to make it useful.
I don't know why you don't just use normal peturbation though...most 
refracting objects won't show much of a difference in surface shading, 
but normal perturbation does affect refraction.
