[Xpert]Using X in a classroom environment

[jurgen . defurne]

Hello,

I am currently investigating the possible usage of Linux and X in a classroom
setting.

For educational purposes, the following should be necessary :
- Each student a PC on which access and usage is restricted, fairly trivial with Linux

But for the usage of X :

- Teacher able to have the display of a student remotely displayed at his own station
- Teacher able to take over all displays of students for demonstration purposes

I have found references to such possibilities on the internet, but not in relationship to
XFree86.

Do these possibilities exist ? Have they been implemented ? Can Linux/XFree86 be
easily configured out of the box for these possibilities ?

Regards,
