Not all of the future possibilities of digital publishing are applicable to poetry. (This is speaking about the poetry book once finished, not about how that book could go through the process of publication. For more on the latter idea, see my post about a hypothetical model for a poetry publisher, wherein the publisher essentially works as an API for readers/consumers to create a poetry book based on their own criteria.) It is useful to trim down these speculative possibilities to look at how the ideal poetry ebook, with its particular requirements, might look (outside of present platforms or devices, although much would be possible within the EPUB3 spec.).
