Hi firebird,

You may want to take a look at org-mtags.el in the contrib/lisp
directory (part of the org-mode distributions, but not in Emacs).
It allows you to use a Muse-like syntax for embedded code
and many other muse constructs, for example

<src lang="emacs-lisp">
...
</src>

The tags will actually be in shadow font like in Muse.
With (require 'org-mtags), very little should be required
when moving muse data to Org.

I would like to give a fixed font to the examples as well,
but I have not been able to figure out how to fontify
large multiline chunks reliably.  I know that Muse does it,
but John Wiegley is still a hell of a smart guy...

I don't know why font-lock-add-keywords doe not work, it should.
I will take a look later.
