The PID is different, yes, but the actual encryption algorithm is identical - that's what I was referring to when I said that it's the same DRM mechanism, and is why, given an encrypted book and an encryption key (the PID), the same code can be used to decrypt a book whether it's been bought from Mobipocket or from Amazon.
