[ih] uucp, was Question re rate of growth of the Arpanet

[Craig Partridge]

According to the wikipedia page (which could be wrong), the pioneering
Telebit Trailblazer didn't show up until 1985, by which time USENIX/UUCP
was already quite big.  So something else must have been in place before
then -- or was the fact that ihnp4 was willing to run up a huge phone tab
hide many issues?

Side note: the web page also noted that Telebit was founded by Paul Baran
(small world department).
