Well, i strongly doubt anyone would need to do that.  Right now, there's
enough long-haul fiber capacity in US to provide _all_ current Internet
customers with full T-1s.

Some carriers (Qwest for example) are already in terabit range in terms
of raw capacity.  Switching capacity is an entirely different beast :)

Caching is not a panacea; it is not going to reduce traffic by even an
order of magnitude.  Simply put, the diversity is way too high.  A year
worth of Internet growth...

I would rather think of cacheing as means to reduce load on very popular
servers, not as something crucial to fixing backbone capacity problems.
