I totally agree with your current insight that we need to seperate
the routing from the host identifier. IMHO every host should have
one globally unique ID and could have multiple transports, even if
those are IPv4, IPv6, IPX or whatever based and going over multiple
links or not. Though we should limit to IP based protocols to not
make it too complicated. Such a mechanism could solve problems for:
"site-locals" constructions, multihoming, mobile-ip without hindering
the size of the routing table as people could continue to use current
routing, thus TLA based and fully aggregated to the TLA level in the
GRT.
The multi6 wg has been working on locator/identifier separation as a
way to solve the multihoming in IPv6 problem for a while now.
The problems we're facing (apart from the fact that there are many ways
to skin this particular cat and everyone has a different preference) is
that additional mechanisms are needed to get the extra information
across, and there is a price to be paid in one or more of: additional
round trips, more dependence on the DNS or something similar to DNS,
additional per-packet overhead, loss of backward compatibility,
increased complexity.
