I'm not sure, what you mean by an "official" release. I'm attaching
the org-mm.el file here. Please add it to the EXPERIMENTAL directory,
if you think that's the right way to go about it. Otherwise, tell me
what would be the best way to "officially" release it.

Sorry for leaving your name, against code that you didn't write. I
had been using this exporter for a particular task I had been doing,
during a period of time. Didn't really bother about minor details and
making the code public.

;; the org-export.el experimental engine.
;;
;; Put this file into your load-path and the following into your ~/.emacs:
;; (require 'org-mm)
;;
;; You also need to fetch Org's git repository and add the EXPERIMENTAL/
;; directory in your load path.
;;
;; Fetch Org's git repository:
;;
;; ~$ cd ~/install/git/
;; ~$ git clone git://repo.or.cz/org-mode.git
;;
;; Put this in your .emacs.el:
;;
;; (add-to-list 'load-path "~/install/git/org-mode/EXPERIMENTAL/")
;;
;; Export Org files to MoinMoin: M-x org-mm-export RET
;;
;;; Todo:
;;
;; - handle radio links
;; - support caption and attributes in tables
;; - better handline of source code and examples
;; - handle inline HTML
