Puneeth If you are so inclined (and wouldn't mind wasting away some hacker cycles), you could use org-lparse.el for creating the moinmoin exporter.
Start with my test.org and org-odt.el and just go with the flow till you get the expected org-moinmoin.el. I was able to create a "works for me" docbook exporter in about a day's time. If you actually take up my suggestion, I would really like to see your notes on both your org-moinmoins. Jambunathan K. --
