   I was discombobulated and enervated to see this line from Tony.  The
   plan is largely based on his previous writings.  Apparently, having
   convinced me, he has repudiated his own previous thoughts.

Bill,

You're missing something here.  Topology is NOT tied to international
connections.  The concept of "international" is a political concept
that has limited bearing on the problem in that it affects the cost of
links.  Topology seems to be currently (and may continue to be)
affected by significant geographical constraints, such as oceans.  

The concept of "addressing" must be tied to topology for aggregation
to provide useful results for IPv4.  However, "address administration"
is primarily a political problem.  As such, it is indeed
(unfortunately) tied to international constraints.  Thus, the body
performing the administration is political, but the addresses being
administered are topologically assigned.  I think that you need to be
very clear on the difference between politically based addressing and
politically based address administration.  The former is foolish.  The
latter is an unfortunate necessity.

In any case, any statement to the effect that I agree with ANY facet
of your addressing plan, or any thoughts or philosophy in constructing
it is at best wildly erroneous.

   As you can see, the draft peters out, so I'm not entirely sure where it
   is leading (probably an editting error when he submitted the draft).

Your copy is corrupt.  The version that I have via shadowed anonymous
FTP is complete.
