Below is a snip from a thread on ltsp-discuss regarding control of
terminals.  Just thought it interesting given the recent problem with
vnc-reflector on Fedora Core 3.  But I don't know if there is a
non-German version.

I've written exactly for this a tool named "vnc-eye" - perhaps you 
understand a little bit of german, so you can look at my site

The features are:
getting the screen of pupils-client to the teachers screen --> the 
teacher can manipulate the screen of the pupil
you can send the teachers screen to all (or only some of them) the 
pupils screens
you can send x-messages to the pupils screens (e.g. "shut up ;-)" ) you
can switch of the screens of the pupils (the monitor will be blank)

To use all of these features, the teacher have to sit in front of the 
terminalserver, because I use the rfb-server (it's very fast) and this 
tool have to work at the machine you are working. at.

Kind regards
