[rrg] Smart host, dumb network - core-edge-sep. doesn't alter this

[Robin Whittle]

Short version:   A core-edge separation scheme is more in keeping
                 with the Internet tradition - where the host is not
                 concerned with moment-to-moment connectivity changes
                 in the network - than a host-based system which
                 copes with this stuff so the existing routing system
                 can remain simple and unchanged.

                 There seems to be a steep set of barriers to making
                 all the changes required to get everyone to
                 transition to a new Internet with new host stack
                 capabilities and all applications rewritten to use a
                 purely host-name interface to the stack.
