The chance of this happening by pure chance is zero. They really would have to do this intentionally (but it would be a little silly for them to do this). So (for now) I think it would be a good idea to use the Unit Key file: its also equivalent to the Title Key file (for HD DVD). So it would all make more sense.

Yeah. That should work fine.

Sounds good. Especially the V/U differentiation. Blu-rays are bound to get more Unit keys per disc.

I'm probably also creating my own kinds of files for Device/Processing keys and Host Certificates/Private Keys (probably using the some kind of format). Which would also include corresponding uv values and MKB versions and Software player name+versions. But your program will not need these files/keys (until that is you implement the mkb processing and aacsauth stuff aswell).
