this is a different history than the one i lived.  when uunet was founded, the
part of at&t research that had a connection to the internet, was not involved
in productizing the internet, and at&t had no commercial interest in the
internet.  at&t wasn't outrun, they weren't in the race at all in any form.

years later when i was operating CIX, i had to tell several large telcos who
joined up, about the difference between peering and transit, and how it was
that their CIX connection wasn't the only one they were going to need.  and
then there was the day i explained to QWEST why they couldn't use RIP, and
what BGP was.  (yes, this was the blind leading the blind, but there i was.)

that's a new topic.  for one, if that's how things progress, it won't matter
to the end result, since there will be no planned ipv6-only networks until the
larger networks are running dual-stack.  for two, the larger networks are the
ones who can predict their address space consumption accurately and will know
well in advance when the ipv4 pool will stop being able to support their
growth.  but let's stay on topic.

there just is no in-year or in-quarter motivation for a small/medium sized
network to discard the last-mover advantage given the thin margins in this
industry.  adopting dual-stack depends on a "war chest".
