    Hello from sunny SaiGon,

    For training purposes, I want to share one LAN client/server's desktop or
    terminal with many (actually 9) clients on a classrom LAN running SuSE 9.1,
    but WITHOUT giving the other clients any control of the desktop or terminal
    being shared, except as explicitly permitted.

    The ultimate objective is to be able to provide demonstrates of Linux usage
    and administration to a classroom of students while keeping each student
    at his or her machine.

    I've tried using vnc and kibitz already. kibitz is great for sharing terminal/
    console sessions with many clients, each in a separate konsole session.

    I've been able to sequentially share a desktops with several clients using
    vnc by successively sharing desktops in a chain-like process: client/server
    shares with client 1, client 1 shares with 2, 2 with 3, etc., and all can
    watch what is being done on the client/server -- though with successively
    smaller desktops (as vnc seems to require its own top window bar for each
    shared session).

    But the catch is that with both vnc and kibitz, there does not seem to be a
    way to stop clients from being able to control the sessions at the same time
    the instructor is providing a demonstration.

    The best scenario would be if the instructor could selectively turn the mouse
    and keyboard input off on each client while s/he performs a demonstration
    and then return keyboard control to the clients when finished. Even better
    would be to enable the instructor to watch what each client-user is doing in
    different desktop/terminal windows on the instructor's machine after s/he
    returns control of their machines to them.

    Can this be done? If so, can anyone provide information or references to
    how it can be quickly configured?

    TIA
