Install mathjax locally, but get fonts from the CDN?

Question

I have a mathjax installation with customized configuration (used through Sphinx) and need to store it on my server. The server's connection is not lightning-fast, so I would like to offload the largest portion of the data trasfers (math fonts) to the mathjax CDN. Is such split configuration supported or possible?

I don't know about Sphinx, but for a plain HTML file, you would include

<script type="text/x-mathjax-config">
MathJax.Hub.Register.LoadHook("[MathJax]/jax/output/HTML-CSS/config.js",function () {
  MathJax.OutputJax["HTML-CSS"].webfontDir =
     "http://cdn.mathjax.org/mathjax/latest/fonts/HTML-CSS";
});
</script>

somewhere before the script that loads MathJax.js itself. You will have to figure out how to get that into the configuration used by Sphinx.
