If you haven't already, check out http://fontcustom.com/. Its like Font Awesome, except you drop a directory of SVGs at it and it generates a ton of fonts. The project could use help in a few areas including:

- Sprockets asset pipeline integration https://github.com/glaszig/compass-fontcustom

- A PNG sprite compiler for compatibility with IE8, Win7/8 phones, and older versions of Android.

I can't say enough good things about these projects.
