Fiest, LocalFS turns out to have the same problem.  MSIE does not
interact well with method=get and file input methods.

I want/need to collect some metadata along with the file.  Say I want
a file, a title, some keywords.  (And I have some idiots with 80MB files).

I would like to enforce the following:

No two files from a given user can have the same title.
A given file may not be uploaded twice by the same user with
different titles.

With LocalFS, as it stands, it is hard to determine the file that 
was uploaded.  (It is not returned by manage_upload, I could create
an id, but that has its own problems (downloading creates unexpected
files on the client PC's)).  This can be modified, but...

More importantly, it is really hard to see how to handle both of
the conditios above cleanly.  With LocalFS, I found no easy way
at all to combine the error checking implied by the metadata and
the error checking desired for the file name.
