        Bandwidth overprovisioning has worked for most of the
last decade.  It appears not likely to cease being a useful
approach anytime soon.  As time goes to infinity, no one can
predict very accurately, me included.

        Sure.  We run lots of PC boxen with 133 MHz CPUs today.
In setting up a CVS server recently, we deliberately bought
the least expensive PC hardware we could obtain because its
more than enough CPU performance and we could save a lot of
money.  No one in my office is planning any upgrades either
to the new Sun Ultra-3 CPU nor to the 1+ GHz PC CPUs, because
we are satisfied with what we have.
