If the system has an internet connection, it might be that the reading software launches a browser program for external links, and then you are in web-page dominions. I don't know if this is the case with ADE (yes, Adobe Digital Editions) or the iPad. If it has no connection (like my Cybook), it can never work.
But you can alway write the URL of the animation, so that the interested reader can visit it with an appropriate system.
