EPUB and fonts

We had a chat with the EPUB liaison during the CSSWG meeting at TPAC today. 

The following link describes the documents being worked on by EPUB currently : http://www.idpf.org/specs.htm.

Of particular interest is the 'Font Mangling Specification' at http://www.idpf.org/doc_library/informationaldocs/FontManglingSpec_2.0.1_draft.htm.

This is merely a font obfuscation mechanism for the purpose of embedding fonts in the EPUB package (a zip file):

"The proposed mechanism will simply provide a stumbling block for those who are unaware of the license details of 
the supplied font. It will not prevent a determined user from gaining full access to the font. Given the original 
OCF publication, it is possible to apply the algorithms described in this document to extract the raw font file. 
Whether this satisfies the requirements of individual font licenses remains a question for the licensor and licensee."

Given that EPUB and Web Fonts WG reps are present at TPAC this week, I think it'd be ideal for this WG to discuss
the issue and start engaging our peers at EPUB on the matter.
