This is one step above the physical transport layer. Upon it, you can
mount a DNS-like abstraction. However, I simply don't like global
distributed databases. Machines don't need syntactic sugar, anyway.

A solution: you leave a message stream reflector in your home (sweet
home) node, you leave a trail of forwarding agents as you travel. When
two agents discover they communicate via a relais, they snap the pointer,
and start communicating directly. When you move, you report your new cell
address to the last agent. _Very_ limited flooding (just few bits of the
binary ID) should catch you even at Mach 5.
If you move permanently, you give notification to all relevant parties,
so that the bulk gets redirected to your new location. A bounce agent
left in place will forward you the rest, while also notifying the senders
about your address change.
There's a million of ways to make this practicable. The chiefest reason
is that you don't need routing anymore, switches (which are vastly simpler
and dumber) are sufficient. So let's chuck out TCP/IP.
