I would like to get general access to TIPs for occasional use
for when I am not at home, e.g. in some distant city.  I suspect I am
not alone in this.  There are two possibilities: the first is to make
your universal password and account more generally available.  The other
is to allow anyone to get as far as asking a particular computer to
authorize his use of the network.  To mention a complicated case: suppose
I wanted to use ISI from a TIP in Boston given that my home computer is
SU-AI.  Then I tell the Boston TIP to charge it to Stanford giving a
Stanford password.  The Boston TIP transmits the password to Stanford
and asks if it will accept the charges.  Stanford inspects my password
and agrees and all proceeds as at present.  This has the advantage that
Stanford can take people on and off the list of those for whose TIP use
it will pay without troubling the network bureaucracy.  Well I like this
idea a lot and now suggest that it is the way the whole thing should be
done, because then you can dispense with the whole business of applying
to you for passwords.
