	I would have to say the that would be a rather generous 
implementation of a 2-user license. In my experience it doesn't work
that way. It seems close to correct to say that you are allowed
2 distinct (username,hostname/tty) pairs.
Thus if a person logs in on the console and another over a tty, then
no network logins via rlogin or telnet are allowed.

Another example, if userA logs in via telnet from hostA and userA also logs
in from hostB via rlogin/telnet, then no tty logins (including console)
are allowed and no further rlogins except by userA from either hostA or
hostB. Any number of these latter are allowed.

In practice on our 2-user 834's:
"xlogin" is run by init. The console user logs in ( and stays logged
in perpetually running as many clients as they want). Say that 
they then also log in over the ethernet from some host.
Then no further logins succeed over the ethernet even root, except for
more logins by the same person from the same remote host. If it is the same
person from a second distinct remote host, then
"Sorry. Maximum number of users logged in."

This actually seems restrictive. We had anticipated two usernames with
any number of connections via both ttys and rlogin being allowed.

I haven't figured out how it actually figures out the maximum users, though.
There are a few situations where I sometimes seem to get 3 distinct logins.
It would be nice to know what the actual algorithm is ( if login is looking
at utmp entries that have certain values in certain fields, that would
rather easy to circumvent - I don't think that is how it is done)
