Font Awesome is awesome, isn't it? for a long time before, i had to add the font-awesome library to every theme handly, by now i created this module, so every theme can share the library.
The module includes minimal theme functions, and it's easy to be overrided by theme.
It is currently supporting Drupal 6, but soon 7.
The project's page is here:
git clone http://git.drupal.org/sandbox/ispboy/1834648.git font_awesome
