    It is true that the simulcast draft does not help you signal 
simulcast in this completely different way. Has someone written some 
spec on this alternate approach, or engaged with the authors of the 
simulcast draft? Don't get me wrong, both approaches seem reasonable to 
me (at least at first blush, although having the thumbnail video be a 
different synchronization source seems odd), but only one of them seems 
to have been written down in a draft standard somewhere.
