Reuseable orgmode php parser

This looks like a good start. I'd suggest a reuseable php parser for orgmode files. It could then be used in your module for orgmode import and another module as orgmode input filter.
Possibly implemented as stateful parser or two step parser (1. parse to a tree 2. render html). This would enable line continuation, better nesting, completion ( [/] [%] ), … . Maybe some existing python parser can be ported.

I'd be happy to join you on this, let me know.
