I thought the standard for getting into the ARPANET Directory was that you
had a NIC handle and were in the NIC database.  Jake F. probably remembers
far better than I do, but as I recall, this meant you fell into one of
the following categories: (a) the official contact for an IP address; (b)
the official contact for a host; (c) had a TAC account; or (d) were a contact
for some IANA number (protocol, port, EGP AS)...

Even for BBN, I doubt more than 25% of us met that requirement but we were
all on the 'Net.

Thanks!
