Martin Our Medical School are installing a program called Netsupport School in their clusters. It allows a tutor to put any screen in the cluster up on all the machines. This would often be the tutor's screen, for demos, but any student's screen could be broadcast for discussion. There are other individual tutor-student interactions possible. It needs fast machines with plenty memory, otherwise it slows doen a bit. It would certainly offer your minimum requirement! But I've only experienced it in a one-off demo, so a I can't comment on how it works in real life use.
