First of all, yes I was thinking more about spy situations.
The way I was thinking is that, spies normally don't go some place where you suspect to have a secrecy danger/threat (ie open pubic, on a plane), but they infest in some where you put your guard down, (i.e. your home, hotel room), and they can approch you as your girlfriend, hotel maid, etc...
Sure you probably won't read the documents in front of them, but you might left the reader in sleep mode, sometimes even unintentionally, which they can sneak into the device, which allows them to view a supposely protected documents that is being opened.
If we are assuming the PDF digital lock does it jobs correctly, then sleep wake with no password protection is probaly the only opening, assuming the document carrier do not read those documents infront of other's eyes.
So thats is basically my concern.
