Markdownize an Emacs buffer

I am looking for a Markdown variant of the Htmlize addon.

The idea is simple: say, you wish to publish code to a GIST on GitHub, or any place which supports Markdown. You type your code in Emacs, do M-x markdownize-buffer and you get a new buffer containing the full Markdown markup.

Anybody knows if such an addon exists?

Markdown isn't powerful enough to generate span classes. To do this, you need to drop down into pure HTML.

Htmlize will generate a syntax-highlighted version of your code based on your current Emacs theme settings. Take a look at the generated markup: it does this by generating both DOM elements and styles to replicate your current syntax highlighting:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<!-- Created by htmlize-1.36 in css mode. -->
<html>
  <head>
    <title>sha1test.rb</title>
    <style type="text/css">
    <!--
      body {
        color: #eeeeec;
        background-color: #2e3434;
      }
      .comment {
        /* font-lock-comment-face */
        color: #888a85;
      }
      .comment-delimiter {
        /* font-lock-comment-delimiter-face */
        color: #888a85;
      }
    /* [...] */
    -->
    </style>
  </head>
  <body>
    <pre>
require <span class="string">'digest/sha1'</span>

<span class="type">SLICE_SIZE</span> = 20

<span class="keyword">def</span> <span class="function-name">myhash</span>(input)
  <span class="type">Digest</span>::<span class="type">SHA1</span>.hexdigest(input).slice(0,<span class="type">SLICE_SIZE</span>)
<span class="keyword">end</span>

hashmap = {}
inputs = 0
unique_inputs = 0
<span class="type">ARGF</span>.each <span class="keyword">do</span> |line, idx|
[...]
  </body>
</html>

Markdown can't replicate the kind of information here. It's good for translating semantic plain-text into semantic markup (i.e. headers should turn into H1 or H2, **text** should generate <strong>text</strong>, etc.). Which lines of your Emacs buffer are headers? Which should translate into <em> tags?
