I have had a number of mails along similar lines.
I suggest that one needs to think more laterally before dismissing the
project. My ex-supervisor always asked 'why?' when a bold statement
was made:

Why? Why is it not possible to protect against? It is only due to the
way in which some operating systems operate at the moment that screen
capture is possible. This is due to an applications 'right' to be able
to read the screen memory. Why should an application have this right?
Only in the case of screen grabbing, as any 'normal' application 'knows'
what it has written to the screen. It is easy to visualise a screen
grabber that cannot grab certain windows (try grabbing a SysHi window
in a trusted operating system.)
It is fair to say that a useful implementation of the proposed system
should run on more common OS. Is it not possible to apply fixes to
these to allow the required protection?

If copying is free, quick, and simple to do, it is likely to be done. If
many unauthorised copies are made, breeching copyright, the reward may
never come.
