Very far from true. NOS is probably the best reference for TCP/IP over
amateur radio. Its not a good reference for NetROM, ROSE or some AX.25
stuff tho. There's a lot of handy free source around
- NOS
- Linux AX.25/NetROM/ROSE/DAMA slave
- Wampes (NOS with bits like nicely working NetROM)
- TheNode

Actually because of security issues it doesn't. It may do one day.

Very much so.

That's a hoot! "Intranet" was a magazine-writer coinage (or some such) a
couple of years ago to describe what we've been building for many years,
"corporate data networks". It's a lousy term. Corporate packet networks,
using DECnet and TCP/IP, go back a long time. Let's not claim too much
credit here, any more than the Russians can claim to have invented
electricity.
> Classless IP addressing
Phil's NET and NOS programs were good prototypes of that, for sure.
> Same addresing on slip interfaces to resolve net addresses
Huh? Do you mean using the same address on multiple ports? That's one of
the things DECnet has done all along, one address per node, not per interface.
> IP encap solve security and movement (mobile IP) problems etc.
I hardly think AMPRnet can claim much credit here, though my own
contributions towards mobility in RSPF probably predate the IETF work by at
least a couple of years. But it never got really used much in AMPRnet.

Some hams try. Alas, as you note, the "on air" majority remains paleolithic.
Then they claim the frequencies for themselves.

Old-time readers of this group might recall (I don't have the file handy)
some talk about Japanese hams using V.29 9600-bps fax-style modems on the
radio. The 14.4 modems are almost the same but a bit more sensitive to
impairments.
Yes, it works. Sort of. But it's not ideal. Wireline modems are
optimized for wirelines. Running any such baseband-audio modem into an
FM voice-optimized modulator is going to get a suboptimal signal. This
