If routing is explicit, addresses may be either absolute or relative.  By absolute I
mean that the address resolves to something which is the same for every node, e.g. a
domain name.  By relative I mean that the address may be relative to the node doing
the forwarding, e.g. asking node A to forward to B means that A should use its own
address space.

One usecase is anonymous addressing.  For a path A<->B<->C, B can gateway messages
between A and C without revealing their identies.

Another usecase is for heterogenous naming schemes.  For a path A<->B<->C, B can
gateway messages between one naming scheme and another.  Examples of heterogenous
naming schemes are multiple DNS roots, virtual addresses (e.g. where C is really a
subdirectory belonging to B, but A doesn't know that), and proprietary namespaces
like Real Names.
