Make it a HTML or something app so people with other devices (windows, android tablets/ereaders) can make use of it. (perhaps an idea for a startup would be a website/program that lets content producers create these without HTML knowledge. That is, a builder for interactive HTML5 based text books.)

So you are saying that it is easily ported to other devices, but still requires a native application? What requirements stop you from making it an online thing, that people could use with their home computers as well? Or is it just a personal preference?
