The .start/.end properties were dropped in favor of media fragments, which  
the Media Fragments Working Group is producing a spec for. It will be  
something like http://www.example.com/movie.mov#t=12.33,21.16

See http://www.w3.org/2008/01/media-fragments-wg.html and

There has been much discussion about audio "canvas" API:s and I trust this  
could fit into that scope. View source at  
and search for "v2" and you'll find some of these ideas.
