That depends. You don't have to be blind to get the longdesc for images  
 from Opera, even if it is sitting on another page. Indeed, curently in  
Opera sighted people have more ways than blind people to get value out of  
longdesc. I don't think that is a problem either way (although more  
generally we should be doing better for blind users).

Not necessarily. There is a deep issue I have with ARIA, about claiming  
that it is only for "assistive technology" and thereby *assuming* it won't  
be implemented or wanted as native functionality in browsers. I think this  
assumption is demonstrably wrong (among other things a lot of aria  
functionality was developed to run directly in browsers).

I don't think video is the only element that might need this, but I think  
Sean provides, above, a use case for at least two different long  
description documents...
