file upload extension

Y'know, it could be *really* simple, and done purely from a UA.
For example, instead of plain clicking on the <Browse...> button,
do a modifier+click (like Option+click on a Mac) -- this would
bring up a dialog asking for the data source. The user chooses
"Microphone" for example, and a sound-recording dialog appears.

If the MacIE team wanted to implement that, they could do so
without need of any forms-enhancement spec. It's just a matter
of sending the appropriate MIME type for an audio file, assuming
it's known what the server wants. Well OK, maybe we do need one
small enhancement: wanttype="audio/basic".
So we'd have something like this:

  <INPUT TYPE=file NAME=foo WANTTYPE="audio/basic">

With that info, the UA would know to record sound and convert to
.au format.

How's that for simple and platform independent?
Just specify the syntax for that one MIME-related attribute, and
we're all set. The rest is up to the browser developers.
