Suggestion for caching servers supporting multimedia broadband channels

Guam's bandwidth SUCKS at night. I'm messing around with my Motherload playlist (see what clips I've got stored) at home just before 8am on Wednesday on my 3.3 Mbps cable modem connection. Comedy Central's broadband channel works perfectly, and I've got no long buffering episodes, playback slowdown reminiscent of Street Fighter 2, or any waiting at all. I'm jumping from clip to clip and getting real-time results. This is in stark contrast to nighttime browsing, when I've got to fight for every bit.

I know from my days in the local ISP game that Guam's notoriously limited bandwidth can't support the growing number of users interacting with pipe-intensive applications during peak hours, generally weeknights from 7-11pm. (It's the same problem AOL used to have, circa1995.)

I don't have a ton of experience working on caching servers, only having messed with Squid and Akamai, but I'd like to make a suggestion for those involved with their development, especially for those supporting multimedia for broadband services. There should be a way to cache at least the first half of a clip, such that a user can start watching the first 2:30 of a 5-minute presentation from a server cache, while the remaining unloaded bits are streamed to the client app.
