Not so much WAN/LAN (the PUP network had both LANs and WANs), although
inclusion of WANs does bring in some issues, e.g. adaptive timeouts.

I think a bigger factor was that TCP/IP was at least attempting to build a
_large_ network, and also starting to think about the issues involved in
building a 'multi-owner' network (which of course are not just technical, but
also managerial). Anyone can build a small internet, but scaling it up is
really hard.

And that feeds in to what I still think is the killer - Metcalfe's Law, and
the user base size. I had a saying I used to people at Proteon (many of whom
were still focused on LANs) a lot: 'The neatest thing about the phone on
your desk is not that it can call someone else in the company, but that it
can call anyone anywhere.'


PS: I would be great if this list could focus on _one_ topic at a time.  This
ping-ponging from 'total silence for weeks' -> '4 active threads at once' is
not optimal if the goal is carefully thought out replies. You (non-specific)
have a topic you want to discuss? Stick it in your pocket until the list goes
quiet for a day...
