Using a 1D numbering plan to support 5 (?) distinct dimensions (plan,
technology, network routing, global host addressing and interface
identification) looks like X121 or old telephony.
Which additionnal information do you need to move accross if you use fixed
size dimension and gives evey dimension its separate numbering
authority/structure and then concatenate them into a multidimentional
address? Like for mobiles.
I remember when CCITT voted they would never allocate addresses of more
than X bytes. (was it not 32?). Would anyone recall if at that time they
discussed some kind of layer splitting? Old experience often carries
interesting concepts. They were probably thinking hierarchichal instead of
multidimensional?

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.
