Articulate Mobile Player (AMP) End Support?

I also rely heavily on the offline capabilities of the articulate mobile player. There are a few existing apps that I have found recently that will play the courses offline - most file manager apps do not. Document GoGo (although the player is tiny) is one that works and My File Manager (has adverts though) is another. However, because you need to zip a published web version to get this to work offline, the user then has access to your entire file structure including copyright images and sound files etc. Does anyone know of a way to hide/encrypt the files/folders within the zip so that only the story.html file is visible/accesible?
