Agreed. There have been a couple of occasions at work where a  
marketing guy came by and asked me if I could "get the Word document  
out of this PDF." The person in question quit, deleted the source  
documents, and locked the PDF. I was able to unlock it with very  
little effort and recover the text.

I've said on a number of occasions, PDF "security" is akin to leaving  
the door unlocked and putting up a "Keep Out" sign. It's easily  
ignored if you have a reason.

Having said that, the OP could set the "security" bits in Ghostscript  
while creating the PDF. See the GhostScript "Ps2pdf.htm" page and the  
PDF reference found at:
