Ragel http://www.complang.org/ragel/ is a tool that integrates regular
expressions and state machines under one umbrella.
It has backends currently for C, C++, Objective-C, D, Java and Ruby.  I do
not think having an elisp backend would be a very big task.

After that (in my estimate) org-mode code would (could) become half as long
and twice as fast -- at least those sections that are heavily regex oriented

I took the freedom to add your (slightly modified) proposal to the GSoC
2012 ideas page:
http://orgmode.org/worg/org-contrib/gsoc2012/orgmode-gsoc2012-ideas.html

Perhaps related to this proposal would be a project to formally specify
Org-mode's syntax.  I'm thinking this could be an extension of the truly
remarkable formalization work recently undertaken by Nicolas in support
of his Org-mode AST representation and exporter, but with more of a
focus on specification in such a way as to facilitate developing
Org-mode parsers in other languages, be they Ragel, OCaml [1], VIM [2],
Haskell (e.g., pandoc [3]), or scripting languages to allow exporting
without Emacs (e.g., a replacement for org-ruby [4]) for use at github,
wikis or any website in which Emacs is too large of a dependency.

Cheers,
