I think `org-mime-org-buffer-htmlize' and `org-mime-htmlize' from
org-mode/contrib/org-mime.el by Eric Schulte are able to handle
composing rich html mail.

From a quick test, it seems to /almost/ work:

- images get attached, depending on the mail client they may or may not
  get displayed inline (Gnus shows them inline, roundcube below the
  message body)

- /css/ and /js/ appears to be missing, which breaks pretty formatting
  of code-blocks and mathjax for TeX.
  Setting #+OPTIONS: LaTeX:dvipng  as suggested by the Org info manual
  causes an error about a missing temp-file.

The file used for this test is attached.

Maybe these are just configuration quirks and could easily be dealt with
by setting the right options in org, or someone familiar with `org-mime'
could take a look at what's going wrong?

There was a bug in Eric's code which was fixed a couple of
days ago in the org mailing list


The original code was 
;	 (org-export-with-LaTeX-fragments "dvipng")
but it should be:
	 (org-export-with-LaTeX-fragments 'dvipng)


Yes you are right this is very nice. However the way the
attachments are inserted in the text is ugly at best. I just
tested in thunderbird an extension called latex-it and it
looks much nicer, but it is not emacs :'(

I think the reason for this ugliness is that *mml* does not
support something like floating elements. I wrote a small
rant in the org mailing list but nobody replied. I think
will post it here.
