Hi folks, Friday (3 April 1998)

I can't resist shooting these ducks in a barrel. The IETF does NOT only
publish protocols over TCP/IP. For ten years there have been IETF
standard mappings for SNMP (their ONLY 'standards track' net management
protocol) over six different transports. The change log of the latest
revision of HTTP (draft-ietf-http-v11-spec-rev-03.txt, 13 March 1998)
shows updates to REMOVE any impression that TCP/IP should be the only
transport.

Mapping IPP over multiple non-Internet transports is entirely suitable
for an IETF 'standards track' document. The IETF gave up on Internet
suite everywhere a LONG time ago.

Cheers,
- Ira McDonald (High North)
