However, LISP does have non-Internet applications which are
interesting.  You can potentially have multi-homed connectivity
between your own branch offices, using one or more public Internet
connections at each branch, and your own private mapping servers which
know the state of reachability from one branch to the others.  In
effect, it can become "poor man's L3VPN."

Beyond non-Internet applications such as this, I think LISP is useful
largely as a case study for what happens when a bunch of engineers get
together and "solve" some problems they do not understand -- DFZ
size/growth being chief among them.

They moved the problem along, that's what indirection does.

to borrow from david wheeler:

"All problems in computer science can be solved by another level of
indirection... Except for the problem of too many layers of indirection."

It could be that ultimately what passes for end-system/network
multihoming moved up the stack to application layer overlays that
already incur the overhead associated with building such a topology.

Like others, I still leave room for the possibility that I am wrong about this.
