[TUHS] BSD/v8 TCP/IP (was Shell control through external commands)

Two big debates I recall:

	Datagram (packets) versus virtual circuits (telephone calls).

	Berkeley (BSD) sockets versus Bell Labs (dmr) "streams" APIs.

It is important to note that the STREAMS stuff that eventually was foisted on
unfortunates from USG in System V was  - despite being derived from Ritchie's
work - yet another ... thing.


dmr was trying to replace the abomination that the tty drivers had become (and
I still wish we'd adopted his APIs and work for that purpose to this day),
but trying to force everything into a connection-oriented framework for a
datagram/packet network has conceptual limitations, and to AT&T's chagrin,
the Internet is not an X.25 or Datakit network.

Plan 9 also had some interesting work in it that I wish we'd adopted.
