 I just re-read GRUU and realized that, for some 
reason I thought public GRUU was specified as 
a type of AoR in the spec. 

 I guess the question then is whether we want to 
expand the semantics of "rc" to include GRUU's 
mapping to contact address.
 
 After all GRUU can still be identified in the H-I 
using the "gr" parameter, so keeping the text 
as is may not be such a big deal. So may be 
adding text to identify GRUU in H-I is all we need.
