So far we have said (rightly or wrongly) that the actual fetch
of the actual fetch of the referenced document was outside the
scope of IPP. For example, an implementation might use FTP
to retrieve a document. If this were the case, then don't we still
get by with just an origin server? Do you thinnk we need to add
the fetch to IPP and use HTTP for this?

One objection that was raised to the use of HTTP as a 'transport'
was that it might require substantial complexity. In response, I
among others pointed out that only the 'origin server' requirements
of HTTP would apply. If print-by-reference is a MUST, then most of
the HTTP client requirements would be equally applicable.

As I said before, I believe that specifying how this works if
present is a very good idea, but I believe that whether or not to
put this feature in any given product should be a choice left to the
vendor.

This strikes me as an easy feature to describe as a very small set
of attributes which describe whether or not print-by-reference is
supported and if so what identity the printer is configured to use
and any network access restrictions it may have.
