Oh man, do I have an idea for you: subtitles! use mjpeg for video with just a black frame use whatever audio you want a modern container format and a modern subtitle method will let you put whatever characters you want where ever you want on the video. Boom a video that plays and the "textual" information is kept intact and can even be demuxed from the multimedia stuff. I leave the actual implementation as an exercise for the reader. -- The Mafia way is that we pursue larger goals under the guise of personal relationships.
