I want to use VNC for classroom training purposes. so I want multiple users (students) to be able to view my shared desktop, but I only want them to view. ie not change anything. I had a look sat the VNC docs but couldn't see anything obvious.

Which VNC server? RealVNC? – slhck Feb 3 '12 at 11:49
Most VNC servers have obvious checkboxes for read only modes. – sinni800 Feb 3 '12 at 12:14

With RealVNC, there are tick boxes under the "Inputs" tab of the server properties that you can uncheck to prevent input from clients.

  • Accept pointer events from clients
  • Accept keyboard events from clients
  • Accepts clipboard updates from clients
