Scheme Textboard Development

So, since I've been making headway on the FastCGi daemon and all that, one thing I'm not looking forward to is writing the BBCode parser in Scheme.

Does anyone know of a BBCode implementation in Scheme? Or can anyone make a sane one in (mostly pure) Scheme?

Here you go: http://pastebin.com/QF8q0tx7

It's a Base64-encoded .tar.gz archive. It contains the leiningen project.

I missed some test bullshit while cleaning up, and note that there are slight differences from what the Clojure code would be from Clojurescript in the parser, but I think I commented them, and they otherwise should be quite simple.
