Good. So, at least we seems to agree that we do not need LISP
to deal with the routing table size.

LISP is *not* going to reduce the cost of multi-homing. To the
contrary, LISP is going to make the cost of multihoming higher than
it is today. This is because deploying and operating additional
infrastructure/mechanisms to support LISP has its own (non-zero)
Moreover, LISP would would place this cost not only on the enterprises
that want to do multihoming, but on other parties as well (which
would result in mis-alignment of cost relative to benefits).
