I think that could work. If UAs read and respected that information, it  
should be robust enough for producers.

Flag in the markup could be carelessly copied&pasted by authors, so  
information embedded in the file itself (where it's harder to set and also  
harder to lose) seems to me like a better solution.

Disabling of whole context-menu is what I'd like to avoid. It contains  
other options that users care about (mute, full screen), so it would be  
best if UA disabled saving/copying of URL with no loss of other
