Actually, the little blue bar in the lower right corner is a
standard place for the progress bar. Unfortantly It isn't as
'friendly'.

I'm aware of how the patch you originally proposed works. The
issue I see is if we're making changes to how uploads work within
php, It would be nice to be able to, easily, do other things like:

  - authenticate a user before accepting a download
  - stream the download through an encryption algorithm.

You can provide a progress bar, as php stands right now, without any
patch.

you've been hearing about.  No, sir.  Our model is the trapezoid!
