I see about a tenth of Arthur's traffic through squid, but the
percentages are about the same. I've seen savings drop from over 20%
to around 15% due to the rise of streaming media.

Streaming media (by which I mostly mean YouTube) easily count for 40%
of HTTP traffic. I'm experimenting with YouTube caching at the moment;
so far I'm seeing about 30% savings, which should get us back closer
to 20% savings overall.

What we really need is an extension of HTTP that allows a
Bittorrent-like collaborative transfer, with the addition of
nearest-neighbors only, and reporting of stats back to the original
HTTP server for hit counting. I know there are sites that do things
like this with Java or Flash, but until it's in apache and Firefox, it
will go nowhere.
