ejabberd 1.1.4

The vast majority of rooms will not be used, and I suspect that client
service discovery will choke when loading an index of thousands of rooms.

So, I'm taking a different approach.  The idea is to create the rooms on
the fly; the room is created when the first person joins, and it is
destroyed when the last person leaves.  I'm still working on some of the
implementation details, but basically it will consist of a web page that
lists the students' classes, and when they click on a class, a bot will
send out a muc invitation to the user to join the room.  This has the
extra benefit of being client/server agnostic.

This is still a work in progress, so I don't know how well it will
actually work.
