IMO we should look closely at the CuenEntry and seeking functionalities
we'll (not) have with all proposed systems.
Also in Mosu's proposition would the TrackUID and other elements have
the same EBML ID as in other places of the format ? There are pros and
cons for both. But frankly TrackOverlay is not so different and much
more consistent with other existing apps. Any current Matroska player
will only play the first video track anyway.
