So... use the existing jobqueue infrastructure, and just use your 
post-processor/decryptor as a user job.  You would have to track 
upcoming recordings in the scheduler, and handle tuner locking through 
mythprotocol, so your use of the CAM would not interfere with MythTV's 
normal access to the tuner card.
