Wow. So many serendipitous interconnections that we weren't even aware
of back then. That paper that Bob got from Steve is probably what Bob
showed us back at MIT. Both Bob and I were in Licklider's group, which
had the ARPANET IMP and did lots of associated networking projects,
e.g., Bob designed and built the IMP interface for the PDP-10.
Alohanet had more probability in its genes than East Coasters were used
to -- so it seems "undisciplined". But IMHO Alohanet couldn't be done
on the East Coast because we didn't feel the same pain there as those in
Hawaii. Too many separate islands in Hawaii with very deep ocean
separating them. Wires were out of the question, so radio was the only
choice if they wanted to communicate.
That was the "scenario" that motivated creating whatever they could get
to work and try unconventional, undisciplined, approaches that weren't
needed where you could easily get more wires from the phone company. If
all the states east of the Mississippi were separated by deep submarine
canyons, Alohanet might have been developed there...
