Finding ways to force object revalidation by an intermediary cache (so
the end origin server knows something has been fetched) and thus
allowing the cache to serve the content on behalf of the content 
origintor, under their full control, but without the bits being served.

I'm happy to work with content providers if they'd like to point out
which bits of HTTP design and implementation fail them (eg, issues
surrounding Variant object caching and invalidation/revalidation) and
get them fixed in a public manner in Squid so it -can- be deployed
by people to save on bandwidth in places where it still matters.
