No, it doesn't (records *of the requests* are required, but no
obligation to create subscriber records exists).

Even if it did .. academic institutions are exempt (to CALEA) as private
networks.*

There are various legislative attempts afoot to create one here in the
US .. but none have passed.

There is a great deal of uncertainty about the issue of academic
institutions being exempt. I know tha that the opinion of the
University of California's Counsel was that the wording in the last
CALEA update a few years ago removed that exemption and a representative
of the FBI, speaking on CALEA requirements, was explicit in saying that
they were not exempt. (Of course, that would be the FBI's position.)

In any case, get your own legal opinion about this. Don't rely on NANOG
for legal advice.
