sorry if it was already mentioned, but what many universities use for caching is (open src) squid:
http://www.squid-cache.org/Versions/v3/3.0/ ftp://ftp.squid-cache.org (software development originally funded by NSF (i.e., US taxpayers) to support research into performance and scalability of caching. i've been looking for a paper for 5 years that compares the performance/costs of akamai vs more open platforms on either the end user or access provider, but have never seen any.) from squid author, Duane Wessels: You'll have to decide how you want users to reach Squid. You could write a "proxy.pac" file and then encourage folks to use it. But if its voluntary you might have a hard time getting enough takers. A more aggressive approach is to use WPAD (DNS and DHCP tricks). The most agressive way is to intercept port 80 traffic on a router and shunt it to Squid.

Not sure if Marlon is paying by the bit or dedicated or 95%, but Akamai also uses your bandwidth to reach other customers close to you from the servers they place on your network. I think if someone was colocated in Seattle, they could maybe just peer with them. One way to avoid some bandwidth costs.
