Mark,

This is called "refrying" in the Acrobat world, and if security is 
present and you don't have the password, you can no longer get away 
with it. How Adobe managed it, I have no idea. The PDFZone forums are 
rife with this kind of project, and with people who have legitimate 
reasons for removing security stymied by the present PDF format.

The gist of the security issue is, if it's present, you can't easily 
break it. (N.B.: I don't say it can't be broken. Adobe thought it had a 
secure encryption method with eBooks until Dmitri Skylarov spoke at 
Defcon and got arrested.)
