Well, you've got their name from their login, so you don't need
to gather that information again.

You can gather the actual time that they used the computer
without their intervention from the logs.

That leaves "purpose", which will be filled out by half the
students as "class work" and the other half as "rberbwbbe"
or other keyboard mashing.

Preventing use of the computer is a difficult problem: see the

which gives me an idea:


Make xscreensaver start at login time, and add your application
via "xscreensaver -command watch". It's less ridiculous than
many other notions.
