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.
