That idea is not just focused in IPv6. An identifier agnostic (generally speaking) experiment is underway in the IETF.
Take a look at http://tools.ietf.org/wg/lisp/
or for a less onerous read http://lisp4.cisco.com/lisp_over.html (the description and the rationale in this isn't perfect IMHO, but good enough for the basics)

Its an evolution, given how far and how fast the internet has come compared to almost every other 'fast mover' technology - if the network fails to evolve, it will fail. But I guess I'm preaching to the collective choir on that ;)
