Could I sell an ePub document in the apps section of iTunes? I know I could sell it in iBooks, but I think this particular project might sell better in the app store. I am completely new to ePub, I am just trying to wrap my brain around how it works. I noticed there is a "Books" section in the app store, is it possible any of these are eEubs? Or do you always need to open an .epub file inside some kind of a reader?
