You're right—separating these into perhaps an Extensions directory makes sense (after all, people don't normally need both Textile and Markdown, and I'm not brave enough to pick one over the other to be default).

As far as Markdown / Textile parsers, I don't know any in Objective-C, but I'm sure there are good (if not the original) implementations available in C.
