A multimedia book using the Baker Framework is sold as an App. Apparently consumers are not finding the books because they are lumped into the gazillion Apps on the market. My book would have been competing with a Fart Sound App instead of being categorized on a 'book shelf' under memoirs. Now that we know this, the book will be created using EPUB the same way regular e-books are programmed. By doing this my book can be sold where books are sold in the iStore. Putting stuff off can be good sometimes!

I just received this email from Amanda of Digital Bindery (http://www.digitalbindery.com/) explaining the format she will be using.
I am going to create an enhanced EPUB 2 that will be more like EPUB 2.5 with EPUB 3 architecture built in so that it will be useable on all of the tablets (including Nook Color, the Galaxy, etc) and be EPUB 3 compliant. So, while it will be technically both EPUB 2 and EPUB 3, I wouldn’t market it as an EPUB 3 yet because it may confuse more people than it attracts since EPUB 3 hasn’t been widely adopted yet and we don’t want people to think they won’t be able to view it on their device. The book will be sold in the iBooks store under Enhanced Editions.
With the technology available today, one can record quality video very easily. Many of you are releasing books with a niche market. I see Yoga books, self-help books, auto books, etc. These are perfect for a multimedia e-book. Most of the top sellers at Vook (vook.com) are non-fiction practical books. There would be more investment associated with production than a normal e-book but once it's done it's done.
I'll share more as things progress. Hoping to launch in a month.
