Comparing single-administration networks to the Internet seems a
little apples-oranges.  Lots of things get easier if you can
administratively control load and mandate which versions of which
applications get deployed.

But, setting that aside, what do you think the Internet should
have learned from Xerox/3Com/USMC about, say, congestion control?

Or what other specific insights or technologies do you believe
the IETF wrongly rejected?
