I am interested in some programs that allow a priviledged user to watch
another user's terminal, and/or (especially AND) to allow the prived user
to type things on the other users screen, as if he was sitting there next
to the non-prived user.

For example, if a student were to send me mail about some error, instead
of having them come to my office (oftentimes they are offsite users) I
could "advise" thier terminal, have them re-create the error, and see
exactally what the problem is, and possibly fix the problem on the spot.

I know commercial products like this exist, but are there any floating
around in the public domain?

Thanks!
