Dear J. Bloom, I have an idea and I hope it will help.
In 1956 N.J. movie theater flashed subliminal messages, "Hungry? Eat =
=3Dopcorn. Drink Coca-Cola." This increased popcorn sales 58% and =
Coca-Cola sales 18% but results were =3Dot replicated as it was felt =
that people were subliminally affected and =3Dad no choice in the =
matter. Psychological warfare it was coined and this =3Daw was forbidden
= to be used. Maybe you could put this idea to good use by =3Dnsuring
that = a message is flashed in the movie at every specific time =3Drame
asking = people to refrain from illegally copying movies. This could
=3De done in = a psychologically intelligent manner which would not
disempower =3Dhe = person doing the illegal activity, unyet could plead
with their sense = =3Df only copying what they themselves create.
Research could be done = into =3Dhis line of activity. Using the law and
psychologists in = colloboration =3Dith computer scientist and graphic
Designers. I hope = this helps. You have =3Dlways been good to me and
gone out of your way = to aid me. Thank you. I =3Dave other ideas, but I
would rather wait = incase my ideas are too over the =3Dop.  Regards
