Re: [AudioTF] Some helpful comments from an audio publisher

If we go down that line, we should somehow (not sure exactly how) make a very strict separation in this respect between a packaged and non-packaged version of the book. I would hate to then go the next step to essentially introduce these into a non-packaged, Web version of an audiobook, ie, that the Web URI of the audio book would then lead to… I guess the manifest as a separate JSON file, with no HTML entry page at all. We would open up a can of worm if we did so (origin, vanilla browser, Web architecture, etc, etc).

Also: this should be optional. I should be allowed to create a Web Audio Publication, using a HTML PEP with the ToC in it, package it, and call it a bona fide audio book. In other words, audio user agents should be capable of processing both forms, and it would be _possible_ for a publisher/author to go the simpler way.

Would an audiobook format that is the same as a WPUB in all aspects except the address/entry page/toc be such a bad thing, if those who want it to be capable of being both can just add in the optional pieces?
