VPN history

[Stephen Hope]

Rick,

I suspect you arent going far enough back.

X.25 has supported closed user groups since one of the early standards, and
it was around before that - no idea when - i trashed all my standards docs
for stuff like that a long time ago.

All this was built around the idea of taking features on phone networks and
building equivalent data systems, so the idea was probably already in use on
voice nets before then....
