(And the SVG font file format automatically flips the icons. So you'd need to invert. TOTALLY doable, if with a good bit of effort.)
I'm not sure why an icon font would be easier to use than SVGs. Yes, you only have to reference a file once (the font file), but that actually makes it more difficult to use, because now you have to remember two things: how to reference the file, and how to reference the icon.
With SVG, it's simpler, because everything is usually contained in one CSS rule. Yes, it has a reference to a file, but does that matter from the viewpoint of simplicity? I.e., make another icon? Then just copy a CSS rule and edit it.
Also, using an icon font makes it difficult to substitute a single icon by another icon. Suddenly, you have to start rearranging your CSS. With SVGs not so: just edit the referenced url.
Anyway, I love the font-awesome graphics. Except for a few icons, such as icons containing people (they look too bulky and inelegant, for my taste). But most icon-sets don't get people-icons right.
Often.
In light of what I said, why is SVG support "Pro" feature?
