This will take ages, if ever.

Seems a reasonable target.

Read http://www.ietf.org/rfc/rfc4288.txt. In particular 3.1,
and then some other stuff.

What is your time frame? If you want this to be fast, something like
application/vnd.opera.opentype (see section 3.2).

Otherwise, fast turnaround when submitting internet-drafts,
and serious addressing of comments on this list is probably
the most important. Also, try to talk to one of the Application
Area Directors (Chris Newman or Lisa Dusseault), because you
need one of them for sponsoring through the IESG if you want
to go the standards route.
