I pay my ISP to carry IP packets around. Caching is acceptable in some cases
but not in others.

You control how your information is distributed.  If you do not wish it
to be cached in any meaningful manner by an ISP or anyone else then you
must use protocols that are inherently uncachable, such as those
protected by strong cryptography.

In some cases certainly your cache is in fact a copyright violation.

No, it's absolutely NOT.  You knowingly publish your content in a medium
where copying is an inherent part of the system (at many levels!).

If you do not accept that arbitrary copies will be made of your data
then must not publish your information on the Internet.  Period.  No
amount of ignorance of the medium is a valid excuse in this day and age.


For what it's worth the Digitial Millenium Copyright Act (DMCA) 
explicitly EXEMPTS caching as a violation of copyright. (This only
holds for music and maybe video,  but it is a clear precedent.)
