This is highly unlikely. Apple has very bright people working in the iBook area. And, it has very aggressivce, we would say overly aggressive, attorneys who have written licensing language for iBook Author and the iBookstore distribution agreement screws down how its proprietary iBook file format can be used.
To back up the language in its agreements, iBook Author does not have the ability to export in ePub or MOBI formats. MOBI is understadable, iPub is not.
The problem is that for us and many other authors, layout is extremely important. iBook Author is a very rudimentary layout program that is not capable of producing more advanced layouts such as can be produced with Adobe InDesign. In fact, layouts with both iBook Author and Pages 4 and 5.2 reqruire a considerable amount of tedious work.
Worse, Pages 5.2 is so full of bugs that it is not ready for commercial use. So far as we have been able to determine, Pages 4 files cannot be read by iBook Author. Same with ePub files. Consequently, it is necessary to make large investments in two layouts, one for iBook and one for ePub, MOBI and printed publications. Apple has made this particular area very costly.
In our case, the effort is not worth the cost. The reason is that Amazon has by far the world's largest ebook distribution capability and share of market. The business arragements for retail distribution at Amazon are simple compared to Apple's iBookstore and publishing processes. Consequently, author's need to think very seriously about publising commerical works via iBooks and the Apple iBookstore. Particularly in light of the possibility for copyright disputes.
The really seriouis issue for authors is whether Apple can argue any claims to exclusivity with respect to your copyrights contained in iBook content. Our attorneys tell us there is enough ambiguity about this area that it may require authors to be prepared for a court fight with Apple. That is unacceptable, and we believe attorneys for Apple have far over reached in this area. For this reason, we have decided not to publish any content that we wish to publish in multiple formats, e.g., ePub and MOBI, in iBook format on the Apple iBookstore.
Private distribution is another matter. You can export iBooks from within iBook Author. iBooks exported in this way can be distributed and read on iPads and computers runing the iBooks app. What you cannot do is to sell them. That restriction is contained in the agreement.
Finally, we can find no app that will decrypt iBooks into ePubs. There are apps for converting ePubs to MOBI. The leader is Calibre. Calibre can convert a number of formats back and forth. Calibre also has robust features for addiing meta data. Several DRM ripper apps can convert MOBI to ePub and PDF.
There also are no apps that can create the equivalent of widgets in iBooks to ePub and MOBI formats. That is a bit much to expect.
Of all the many issues and problems with Pages 5.2, the lack of a feature to convert investments in Pages layouts to iBook format through iBook Author is truly the most amazing. Same goes for exporting from iBooks Author to Pages. Duplicate investments are required. Pages and iBooks Author have similar UIs and operate generally in the same way. This would imply that Apple is using a common core file structure, most likely base the international ePub standard. I
It appears to us that someone at Apple has made a conscious decision not to allow Pages documents to be read by iPub Author and vice versa. Same goes with export and import of international standard iPub files.
Once gain and as with the issues in Pages 5.2 and the intellectual property isses in iBooks publishing agreements, it appears no one at Apple thought about what customers might be doing with Pages and what they might want to do with iBooks author.
And, of course, class action litigation against Apple over its "agency model" have complicated things even more. The risk now is that Apple is now in a positoin to drop the retail price of an iBook to $.01, and authors have no control over this. If they did, then authors and Apple would be in violation of the Robinson Patman Act. Amazon and any other distributor of digital books also can drop prices out from under authors.
All of this sets up a potentially difficult dilemma for authors in iBook publishig via Apple.
I hope this is helpful.
