from the source of File.py, in case you hadn't seen it:

        This method is deprecated, use the URL of this object itself. Because
        the default view of a File object is to download, rather than view,
        this method is obsolete. Also note that certain browsers do not deal
        well with a Content-Disposition header.

It's for i18n - the id can stay the same while you can change the
title, and you can also change the method itself.  Always seems a bit
like one two many levels of indirection to me, though.

not really answering loren's questions, but thought i'd chip in
anyway...
