Robert, when you say "burned in" are you referring to time-stamp text files 
included in the media wrapper, of converted to a binary format (.scc) and 
merged with the video asset as pixel data?  If it is the later, it makes it 
impossible to repurpose that text to AT like screen readers and Braille 
refresh bars.

As well, from experience this type of post-production is often outside the 
capacity of smaller and non-professional video producers, which raises the 
bar of entry. I expect to see loads of TextAssociation type content 
emerging - certainly in the nearer future.

Can you clarify? (I'm pretty sure that's not what you mean, but the 
limitations of email...)
