Not really - enlighten us...  Web caching when done responsibly by caching
provider, customer AND content server has no "real" dangers of interfering
with dynamic or time sensitive data.

Prefetching is really the only issue that bridges copyright infringement -
all other content was requested by a third party and not the cache itself
- in the arena of prefetching - where the cache is actively making a
decision to gather the content then you may actually have a point for
copyright infringement - but really a minor one.

You don't need to report back hit stats really - the content provider
merely needs to make "something" non-cacheable with an appropriate http
expires header - it can be something like a 1 pixel gif or maybe the
actual text of the page and take their hits off that - if "your" site
comes up quickly it will reflect better on the dsigner and owner of the
site - caching actually benefits content providers.
