Yes.   I actually suggested a design for solving this problem in an earlier version of the homenet naming architecture document:

https://tools.ietf.org/html/draft-lemon-homenet-naming-architecture-00#section-4

I took this out in the -01 document because I was specifying something that probably ought to be specified in a different document—I just wanted to get it out there so that it wouldn't get patented.   I think this is something that could be done on a demonstration basis right now (modulo figuring out all the steps in the process, which I just sketched).
