[dvd-discuss] Digital Rights Management Gedanken Experiments

I have a colleague who wants to demonstrate the kind of
problems that emerge when companies distribute content and
then "turn it off" after a certain amount of time through
encrypted controls. He is looking for a product that would
help him demonstrate the problem, preferably shareware or
open source. Does anybody know of such products where you
can put a time limit on the display of content? (Even better
if you can hide that fact from the user!)  He wants to use
it on a Word or PowerPoint document.
