Embedding of Mime parts

Hello, I'm new to this group, and I'd like to know if work has already
been done or is going on on this subject.

The problem is the following: how to convey thru a mailcap file that
the rendering of a given part (an image, like a jpg, a movie, like an
mpg, or the output of an application, like postscript), is to be done
in a sub-window of the browser/mailer, rather than in its own external
viewer toplevel.

In the context of the Web, I'd like to be able to say in my HTML

<IMG SRC="http://host/path/foo.mpeg">

and have the browser side display that stuff, whatever it is,
*inline*, not in another window.

I don't want the browser to do it itself, I'd like to be able to
configure my mailcap file on the browser side with something like:

video/mpeg : mpeg_play_embed %s %E
application/postscript : ghostview_embed %s %E

where %E (E for Embedded_info) could be the id of the window (a
browser sub-window) where the rendering is to happen.

I'm not sure if an extension of rfc1524 (mailcap syntax) is needed, or
if a set of conventions would be enough.

There is a whole set of issues wrt embedding in a window system (at
least in X), going from session management (how to tell the embedded
app to go away, to come back, etc) up to geometry negociations, and I
don't want to ignore these, but I think that a generic way to initiate
embedding is needed to start with.

Comments ?
