If option (1) is fine in the states option(2) should be even better.
Because with the current way things work, the file is stored unencrypted.
This means anyone who can access this file (mythweb samba nfs etc.) can play
this file without any restrictions.
But when the file is stored encrypted only people who have access to a cam
with smartcard can watch the file.
So for legal reasons option(2) would be the better solution.
When looking at it this way it would even make sense to move the cam and
smartcard to the frontend.
