Great to hear.

After a quick scan your ob-ledger.el file looks great.  I wouldn't feel
obligated to add all of the functionality listed in the template.  Many
of our language files (e.g. dot, sass, etc...) are very simple.  I think
one of the big wins of our new setup is that language support can be
added in very small increments (e.g. [1]).

Please do let me know when you think this is stable enough for inclusion
into Org-mode.

Footnotes: 
[1]  as a mostly unrelated sidebar I've recently started using the
     following 4-line function in place of an ob-javascript.el, for
     embedding javascript in exported html

--8<---------------cut here---------------start------------->8---
# Allow for exportation of JS code blocks into html
#+begin_src emacs-lisp :results silent :exports none
  ;; just to let us export the js directly into html
  (defun org-babel-execute:js (body params)
    (format "<script type=\"text/javascript\">
  <!--/*--><![CDATA[/*><!--*/\n%s\n/*]]>*///-->
  </script>\n" body))
#+end_src
--8<---------------cut here---------------end--------------->8---

Which allows js blocks in an org-mode document like the following to be
exported using the appropriate HTML script tags.

--8<---------------cut here---------------start------------->8---
# play with the url of my homepage -- HTML5
#+begin_src js :results html :exports results
  var delay   = 150;
  var index   = 0;
  var word    = "eschulte/";
  var forward = true;
  function withTlda(str, ind){
      return str.slice(0,ind)+"~"+str.slice(ind,str.length)}
  function step(){
      window.history.replaceState("", "", "/"+withTlda(word, index));
      if(forward) index++; else index--;
      if(index == (word.length-1) || index == 0) forward = !forward;
      if(forward && index == 1)
          setTimeout('step()', Math.floor(Math.random()*20000));
      else
          setTimeout('step()', delay);}
  step();
#+end_src
