The font mangling spec in question was originally developed by folks
at Adobe, and they were the ones most concerned about sticking raw
fonts in a ZIP archive as being just a bit too exposed to be
considered "embedded fonts" (as described in the linked spec for font
mangling). Adobe's Bill McCoy is secretary of the EPUB 2.1 working
group. So if one wants to sell EPUB on WOFF, which IMO would be quite
reasonable for EPUB to adopt, Christopher Slye and Steve Zilles might
be useful "standard" bearers (pun intended).

Cheers,

(Well, it's one way to make an eBook.) In my tests, Firefox, Safari and Chrome (latest Mac stable releases) are all fine with data URI fonts. Firefox and Chrome fail on linked font files, but Safari actually stores a remote webfont as a font/ttf MIME resource inside the .webarchive.
