But what happens when you need some custom UI to switch among
sources... Or what about camera angles, languages, or any of the other
logically connected things you'd like to bundle together as a single
"video object"? Special logic for handling non-HTML5 video fallbacks?
Logic for nearest-mirror selection? Advertising?
All this can be solved by using object/embed to embed a player pagelet
into your pages, it also works across sites.
Why is special case handling for just selecting among multiple rates
interesting or important?
