Unfortunately, I live in the U.S., where we apparently don't have the
right to watch movies we purchase.  Basically, I can't work on aacs,
BD+, css, or key databases without risking getting into trouble.

However, the java blu-ray menus are on my (long-rage) radar.

This might be required for blu-ray 3D, depending on how ffmpeg decides
to decode the dual streams (maybe it will just end up decoding them to
one, side-by-side, stream).  So, this might be worth hacking at anyway.
