Good thing you're working on this project, we think alike.  This has been
in the plans for quite a while, I just haven't gotten around do it.  Until
now I only had the audio case to worry about, not I have video as well.
Since I haven't given it any thought, and ideas you have as to the
mechansim would be appreciated.  The only things I can say for sure is
that it has to be through the pad interface, and it has to be optional
