One of the areas we are continuing to explore with the eXe project is making educational resources available in a variety of formats, including mobile content delivery. In the 0.23 release of eXe, we've added a prototype of an export function that writes the Notes format used by the Apple iPod. There are several limitations imposed by this format, including being restricted to unstyled text, a strict page size limit, and a design that makes it difficult to include images or audio. However, even with these severe limitations, certain types of read only resources are still usable and are now very portable.
The File > Export > iPod Notes menu item in eXe will prompt for a folder to be used for the export. Within that folder, it creates a new folder with the current eXe package name that contains the table of contents and all of the pages. Simply copy that new folder to the Notes directory of an iPod to make the resource available on the go.
If you don't own an iPod but have some other kind of mobile device that you'd like to be able to get your eXe content onto, try the Text export under the same menu.
