There's a difference, however, between ticking a box and having
individual user-attributable credentials. The two techniques are
focused on different goals, generically binding users to an AUP, without
caring who they are, versus being able to identify individual users on
the network (with more detail than a MAC address).
The proposal here is the latter, which would seem to raise the question
of why individual user attribution is necessary, i.e., why anonymity in
the IETF network unacceptable -- even within the pool of IETF participants.
Anonymous access is available to anyone that cares to get a random
registration ID from the IETF registration desk or the network help
desk. So, clearly that was not a motive.
One reason for using the registration ID was to allow people to use the
network before the checkin at the IETF registration desk. Another
reason was fewer tasks for the people manning the IETF registration desk.
