Geoff,
You do realize that you are talking about an incredible amount of
work, that if one single thing is wrong, the user community will sue you and
your firm out of existance. You are talking about disabling a persons
computer without their authorization, in most states that is illegal.
Now what will be your criteria for recognizing a copyrighted work?
For instance if you were to see "Now is the time for all good" would you
assume it is "Now is the time for all good men to come to the aid of their
country", what do you do when it turns out that is wrong, or what do you do
if the user has split things so to your work shows up in pieces?
Think about this carefully it is a tough problem. Under any
circumstance disabling the computer will get you in trouble.
