  Well that's the "problem" isn't it Gary? Can a protected path be 
created in a general Linux environment (as opposed to a closed-source 
Linux environment)? Could such a solution ever be added to Myth? A 
closed-source, binary-only module that would plug into the front end and 
allow playback of encrypted content streamed from an HDHR Prime to local 
storage.
