It's not clear to everyone. :) I still think the evidence tells you 
infinitely more about the dire effects of bad implementations on 
authoring habits than the merits of programmatically determinable 
associations (such as rapid non-linear navigation and easy content

This is entirely true, but if anything it merely reinforces the benefits 
of a programmatically determinable association between a video and its
