In addition to the above use of MIME multipart messages,
it would be nice to be able to return a html document together with
audio or video, it would eg be nice for my 'esperanto demo', as
it would allow me to combine:
(click on an object, see its name, _and_ hear its pronounciation).

I suppose that one could return a MIME message that contains both
html and audio, but if it is handled to metamail, where does the
html show up? A quick hack could be to write a 'html-viewer' script
that talks to Mosaic via the 'external control' feature (very nice, btw!).
Is there a similar way to do this with the other browsers? Or is there
a better way?

Some time ago someone, in comp.infosystems.www someone wanted to
return in one 'message' both a generated image and the generated html
'envelope' that contains it as inline image. Could this be expressed as
well via multipart types? Could external bodyparts map onto URL's?
If this has been discussed before, are there some pointers?
