Thanks Jeff,
My alternatives that I proposed had mentioned formating for the Kindle, Nook, and several other popular eBooks (ie, MOBI, AZW, PDF, etc.) A proposed book-on-CD (as well as MP3 downloads of each chapter) and also a Flash version of the book (which is still as useless as a DVD but somewhat more accessable and less costly)
Again, thanks for your time and response.
