Is this possible in an eBook?

Hi

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?

Cheers

What will be the format of that ebook?, is it a PDF or a compiled HTML?

The kind that'll open as an .exe, and doesn't need acrobat. Is that the compiled html?

Cheers

.exe would then be windows only version. Wont work on linux or mac.
