IMHO,
Sooner or later our community will catch on and begin to deploy such
technology. P2P is a really elegant 'tool' when used to distribute =
large
files (which we all know). I expect that even the biggest last-mile=20
providers will lose the arms race they currently engage in=20
against this 'tool' and start participating in and controlling the flow =
of
data. =20
Throwing millions into technologies to thwart this 'tool,' technologies =
such
as DPI only takes away from a last-mile provider's ability to offer =
service.
I believe this is one reason the USA lags the Rest of the World in =
broadband
deployment.
Ultimately, I believe it will make sense to design last-mile networks to
benefit from P2P (e.g. allow end stations to communicate locally rather
than force traffic that could stay local to a central office through a =
session-
based router). Then take advantage by deploying a scenario such as the=20=
one you've outlined to keep swarms local. Before we do that though,=20
we need to cut the paranoia about this particular tool (created by the=20=
RIAA and others) and we need to see a few more exec's with vision.
