After showing the spec to Foxx, wordsun, and Corrosive, only Corrosive had a suggestion and it was to allow embedding a list of ID's in the packets to facilitate pay-per-view. In other words, broadcasters could include a list of ID's of various decoder boxes so only specific paying viewers can see a channel. This is in contrast to my current method of handling encryption like Wi-Fi, using a single password for the channel. I told him his one-key-per-viewer idea most likely wasn't feasible since the packets need to be small.
