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.
