Well... It's a "secret" and NOT a "secret". If you look around for the python scripts that detail how to get a Mobipocket PID from a Kindle, that will tell you how a PID is developed.
And the python scripts which decrypt the Mobi DRM will show you how the Pukall cipher (PC1) works. Given those tools, there's no reason to not incorporate Secure Mobipocket support into FBReader.
