Variable ior requires very large amounts of processing power, and is 
rarely of any use. This "could" be implemented, but it would require 
rewriting a lot of code and the end result would be little more than a 
curiousity, so it is unlikely anyone will do so. Most of the things you 
could want this feature for could be imitated by using multiple layered 
surfaces with varying iors and normals.
