Is there a way to make a self-destructible or at least expiring file?I need it for some students to see a doc but that they could retain the doc for only 1 or 2 days. Is that possible?
How could you do it? The simplest way could be distributing a proprietary application as the only way to see such documents (i.e. document format is proprietary and, possibly, documetns are embedded into the application). And I have to say that's by no means simple. :)
