Using VNC for a One-to-Many solution...

[Robert S. Huss]

The key issue is efficiently sending signals to multiple machines without a
cost related to the number of clients.  I think your additional requests
are not addressable by VNC.  If I were to use this in our classroom, I
would not want to force full screen or locked out keyboards.  Certainly I
would want the VNC client to be read only, but I wouldn't otherwise
restrict the client machines.   Any additional lockouts should be done
separately from a VNC solution.  I would also still expect it to be the
clients responsibility to ask for a signal.
