Your argument has major holes in it. The cost of bandwidth is going
down, yes. How do you know the cost of local caching won't go down
Basing long term standards and protocols on short-term relative
pricing shifts is not good planning.
Inherent laws of physics say that caching material closer to the
end consumer is cost effective when there are multiple hits.
Factors that could make local caching more viable include:
a) Higher broadband penetration. Long-haul lines feeding dial-up
customers are one thing, customers with fat pipes that want
music and/or video streamed is another.
b) Potential for "mass appeal" content -- such as music and video
would increase the "hit" rate.
c) Municipal networks could expand the realm of what is "local"
allowing caches to operate over a wider audience and still
have cheap local delivery.
d) A content networking standard would reduce the overhead of
managing edge caches -- thereby making them more cost effective.
Standards should be technology neutral, not trying to declare certain
options to be dead.
