one might consider that localized services or peer-to-peer traffic
might not want to burden the long-haul links, for the cost of a 1g or
10g port on a local switch/router.

this conversation is sort of like the ipv6 part earlier though... 'if
people want to do this, cool! if they don't or can't for $REASONS also
cool.'

it's not clear that a flix cache would rate showing up at an IX in
(for example) juneau... though it'd sure be interesting to know the
share of traffic your 4 exemplars contribute to the overall longhaul
traffic mix.
