I hate to comment on blog posts, but I noted this:

<<
A recently proposed behaviour for handling media segments involves placing 
the segment specifier into the Range HTTP Request header, with a new units 
of seconds.

To retrieve the URI http://www.example.com/media.ogv#t=10:

GET /media.ogv?t=10 HTTP/1.1
Host: example.com
Range: seconds=10-

Why /media.ogv#t=10 has been translated to /media.ogv?t=10 ?

Your automagic resolving using X-Accept-Range-Redirect: bytes seems to 
imply that http://www.example.com/media.ogv?t=10 is roughly equivalent to 
http://www.example.com/media.ogv which is definitely not the case. You 
still need to locate the resolver in one way or another, but not by 
crafting a new URI based solely on the structure of the media URI.
