I'm kinda in Jay's camp, I'm not sure anymore what the desires of the WG
are anymore with regards to what we were thinking about....looks like
another agenda item for the meeting.

I was really hoping the IPP WG would be constrained to *only*
handling print requests over the "Internet", and that the more
functional host-to-device protocol would be addressed via a
different project within the PWG (or WG under the IETF, if
that's
preferred).

If I read Roger's approach correctly, it would appear that
TIP/SI
is being used as nothing more than a thin wrapper around IPP in
exactly the same manner as the HTTP approach. This is highly
undesirable, IMHO.
