Right... However, why is that really a problem?  I can see some reasons
to potentially assign the student a /56, but, I think that /63s are
probably not a great idea if they can be avoided.

Sure it could.  Each room could be dubbed an organizational unit or

Right.  If they aren't going to be an LIR, then, they should get a /48.  If
they're going to function as an LIR, then, a /32 is in order.

I'm not so sure about that.  I think that universities that are not going
to act as LIRs should be counted as part of their upstream LIR customer
base for addressing.  Universities that do intend to act as LIRs should
get their own space from the RIR.

I don't think that is broken under current policy.
