A front-end dev friend of mind asked for code-embedding/syntax highlighting too! I'd be happy to add it if I can come up with an elegant implementation. Is there a "markdown" for code that you know of?
I don't know what language you're using, but here's a Ruby library for it: https://github.com/tmm1/pygments.rb
Edit: Scrolled down and saw Django. Pygments is native to Python, so you might be in luck if you want to use that.
