As the long-ago 1:291/51 I agree with what you're saying. I'll also add
that everything you described for FidoNet applies equally well to the
now-defunct global UUCP network, and to the still-kicking amateur packet
radio network. Both can also run over IP.
One of the particular advantages of the packet radio network is that it
can operate on HF frequencies -- though a amateur radio license is
necessary. These frequencies permit global digital communications with
transmitters in the 50-100W range and simple dipole (wire) antennas, and
in many countries permit higher-gain antennas and much higher power. It
is the ultimate in "route around" if I can talk directly to a station in
Japan from Kansas with no intervening telco, satellite, or other
On the other hand, HF is vulnerable to changing atmospheric conditions
and no single frequency is likely to be usable for intercontinental
communications 24/7. Also packet on HF typically runs at 300bps. So,
like everything else, it is no silver bullet. Not suitable for video,
and even photos of any kind of resolution questionable, but does well
with text messages and can hook into the Internet at unencumbered points.
