Doesnt Adobe have a piece of code they use to keep you from coping a 
pdf? I could be totally off here but in a Microsoft conference about a 
year ago a Adobe guy said they had options that would or could detect if 
a pdf was being copied and would no longer allow you to open the second 
and third and on ones. I remember someone making the comment - well 
microsoft will be using that on their OS really fast.
