I think the whole idea is that the PDF and content are encrypted, so editing won't work. As to screenprint, I don't know but Adobe does tout these as features of Acrobat 5 on their site as well. Whatever the security is it's incorporated into Acrobat so they could actually be decrypting it and sending it straight to the video adapter, circumventing screen capture. There's at least one other product that uses that technique. Using a plug-in gives you a lot more capability than displaying an image through the regular html/browser interface. To find out, you'll have to download it and try or perhaps look on Adob'e site for more details on just what the level of protection provided is. If I were hosting images I wanted to protect, I'd take a look at it - who kniows?
