If you are uploading by reference to URL (which presumably the server
would fetch to save bandwidth) then progress information is probably
not something that can easily be exposed by the HTML interface.  You
might want to use an out-of-band ajax-style channel with javascript to
show progress instead.

That's been in there since HTML 3.2, I believe, and was implemented by
some browsers (IE 5-8?).  User interface concerns almost always end up
preferring dynamic form behaviors, with variable numbers of input
type=file elements added and removed on an as-needed basis before the
form is submitted.
