Let me enlighten you, I sit here talking on IRC I am using a grand
total of 0 of the american bandwidth. When I'm connected to an
american mud I'm using very little bandwidth. Reading a web page on an
american site uses no bandwidth once you have downloaded the page. If
a packet switched network allocated paths like the telephone system
and everyone who connected to demon went to the US then yer, we would
be in deep shit. But it isn't, and people don't (in fact a good
percentage of people don't even leave demons own internal network).

Your above maths is highly suspect.

The problem demon have has *never* been lack of knowing what bandwidth
they require, the problem has been that various other parties have
managed to ensure that either does not come online (take the 2nd T1
AGIS line to the west coast for example, it does actually exist but
for technial reasons AGIS have been unable to connect it) or comes
online several months late (take the delivery of every single line to
the original TPOP's as another example).
