[ppml] geo addressing

[Paul Vixie]

# If we could allocate addresses to more closely correspond
# to network topology, then we could do more aggregation and
# the global routing table would see less routes. ...

you never answered my earlier question, so i'll ask it again:

what makes you think network topology is static enough that
this temporary optimization won't cost more in the long term
than it buys in the short term?

# The network topology of today now roughly matches the topology
# of transportation systems and economic flows.  In other words
# the nodes in the network are cities or metropolitan areas.

ok, so restating my question so we can both be sure i asked it:

what relationship does the network topology of today have to the
network topology of tomorrow, and why, and how do you know?
