Actually, this can lead to conflict in today's Internet model.
I think in the long run, with the Content owner knowing things
are going (most likely under their agreement) is going to be
a better operational model. I would expect that semantic
modification will be an agreed upon service (like routing
is today) and certain controls are available to both parties.
Yes, having the content owner provide the proxylet that will
fire when the owner, content combination will be an option.

I agree that this could lead to conflicts between content providers and
access providers. I can think of one good example where access providers
might want to modify the content in their own interest: ISPs offering
free Internet service may want to insert their own advertisements into
requested Web pages (in addition to the content provider's ads, e.g. in
a separate frame).

I see your point. To support this we could introduce references in rule
modules that point to sets of rules contained in some sort of "rule set
library" on the proxy. I agree, however, that this is probably something
that can wait until we have gained some more experience with simple rule
modules.
