I want to make an eBook that dynamically updates elements on certain pages when the reader is online.
So I'd have a website running behind the scenes, and the ebook could retrieve text, video, photos as I upload it to the website. I imagine it would work much in the same way as using an include on a web page.
Is there anything out there that does this? Dynamic eBooks that update in realtime without the reader having to download a new version?
