Including Fonts In ePub?

Heya guys,

I thought of something that would be a cool feature, if it’s possible. Is there a way to include custom TrueType fonts in ePub files? If so, that would be awesome. I have a lot of free fonts I’ve downloaded that are okay to be used commercially, and I’d like the ePub editions of my books to “match” the print versions visually as much as possible in their layout and appearance. So could this be done? Just wondering.
