Password on Startup

We have a Gio@5 in our auditoriums and have awesomely gifted students who like to mess around with things. It would be a huge help if we could Lock the console and require a password to enter the "main editor" screens. IE they are just left on the windows screen until they "login". Any plans on making this happen or is there already a way to do this. Yes i have tried the Shift Esc lock.
