I tried to do that, about a decade ago (1998 or so if I recall correctly), and met active resistance. Not "we are not interested" type argument but "we will strenuously oppose this and take up lots of your time if you persist".

Apparently the original MIME concept is still contentious and some parties, primarily those dealing with email rather than HTTP, think that adding audio and video was a real bad idea and strongly oppose any new top level types.

On the other hand, the model top level type was added later (primarily for IGES, which uses it, and VRML, which does not :) )

I agree, it would make sense.

LV> Any opinions are welcome.

I would be happy to review any such proposal. I have been on the IETF-types mailing list since well before joining W3C, so I have some background there.

I would suggest looking at the proposal for the model top level type, to see what arguments were made for it being necessary.

I would also suggest a strong 'security considerations' section which notes that fonts can be an attack vector and (for some formats) can bring down an entire OS, not just a single application.
