One thing you might want to consider is that the notebook interface
can be configured to save essentially after every change. In that way
one could look at the history of the notebook to see if someone
"cheated"... although this would be very tedious. Unless there is a
history file of commands for each worksheet? That probably could be
implemented, though I don't think it currently exists - it would just
be a text file.
