Just got news that IDPF had been merged into W3C -- a move seems to transit EPUB development to a royalty-free model. Of course there are complaints about W3C's membership structure.

News from W3C and IDPF:

Incidentally found this (http://readium.org/about/project-goals):
Readium is available for both open source and proprietary applications.  For open-source, non-commercial applications, all the Readium code is available under a BSD-style license. For commercial applications,  the Readium SDK code is licensed under Gnu Affero General Public License Version 3 to help ensure the level of development and management support necessary for its ongoing development.
which I think is a misunderstanding of how public licenses work.

"open source" (or "free software") and "commercial" are not antonyms. Rookie mistake.

They're not making the typical rookie mistake, they're doing what they're doing knowingly. Their so-called "BSD-style license" is not a public license. Readium is AGPLv3, or they might sign a separate agreement with you, under liberal terms for some applications if what they say is to be believed.
