Re: EPUB-Experiences making them?

Please keep in mind that the original idea had been to make EPUB completely page-free, with content flowing as needed. Where a page oriented viewer is used pagination would happen in an ad hoc manner, controlled by the viewer, and its configuration through the user. [If you can't think right away of a not page oriented viewer, think of a text to speech presentation of the book content in an audio-book like fashion.]

Those promoting this 'page-free' concept were probably surprised by the fact that the world isn't ready yet to say good bye to the concept of pages, even not for electronic publication content (I agree with Duff that EPUB is probably not a suitable carrier for documents in general). Thus page-related features are creeping in from all sides. The concept of page numbers had to be introduced, and one of the most favourite recently added features is … fixed layout (as in: each page has its own spatial arrangement of content items). So much about theory and practice of 'page-free'.
