IMHO, i wouldnt attribute this directly to a browser implementation. It's 
jsut one way of doing it that is still perfectly valid as far as i know.

one thing that would come immediately to mind would be mimetype.

that is the stuff that the author of the page you are referring to when 
he lists things like

'video/vnd.mpegurl' and stuff like that.

a stream would be likely to include it's MIME type as part of the opening
bytes. the browser would be free to call something else if the mimetype
was not text/html or text/plain, since these are about the only things
that a browser knows how to present natively anyway.

the other thing to note is that most players have significant 'url-ish 
capacities' built into them, so they are capable of accessing urls and 
resolving them appropriately.

i guess that it is true, to some extent. but the boudaries between 
browsers, plugins and players is so squishy as to make the question moot, 
at least in the way you seem to be asking it.

is there a more specific item that you want cleared up?

btw, that page is pretty cool.
