I guess a third party within the network should be useful for everybody, for
instance, to filter viruses.
The issue is to define what role is acceptable and legitimate for that
party.

assuming I understand what you mean by the above, I don't think IETF
should be endorsing such practices at all. I see two pieces:
1. how the content provider makes data available to consumers, and
how it makes the locations of those data known to consumers
2. how consumers find and access such data
the first is under control of the content-provider; the second
is under control over the consumer.
I see no legitimate role for a third party that isn't acting under
explicit instructions from one or the other of the first two
parties. IMHO, *this* is what IETF should standardize.

yes, because there is a need to have standardized interfaces between
content providers and content-distribution networks acting on
behalf of the content providers. there is also a need for a standardized
and efficient interface between content users and content
distribution networks - the stuff we are using now is quite crude.

not sure how to define it better but "closest" (or any superlative) may
be over-ambitious
