If I remember correctly, I had a look at the pandoc option, but got to the conclusion that this way, I would throw away useful 'syntactical' information (for example, I use todo-flags, tags and timestamps to track open tasks).

If you use org-mode without the need to extract such specific information (and are only interested in generating a document), pandoc might of course be a good way to go.

Edit: ...or maybe there even is a hack to identify and extract things like timestamps anyway. I didn't look into it that much.
