Hi Jack,

So, I tried this and you need a really long video to trigger it. I did
it on http://www.youtube.com/watch?v=v_UyVmITiYQ the Google Wave demo.
Browsed to a different video and came back. Then checked the cookies
(which I suspected how they would do it in the current given browser
capabilities). Here it is:

Cookie: FcZDK.resume
Value: v_UyVmITiYQ:2553

I believe the 2553 is the time offset that I stopped at in seconds: 42:33 .

However, I don't think we need to have to worry about this, since it's
not done with URLs.

We could, instead, propose to Browser vendors to implement for videos
and audio files (that are not on a html page) to use temporal URIs in
their browsing history rather than the URI to the start of a
video/audio file. This is within our capabilities.

It would not solve the problem that YouTube has solved, because it
relates to a video on a Web page and I don't think that can be done
any differently.
