After you install the IDPF Readium HTML5 app in Chrome (from the Chrome Web Store), you can read downloaded EPUB3 ebooks (e.g. samples from AZARDI@infogridPacific).
An HTML5 packaged app (A) (see also W3C Packaged Web Apps specification) and an EPUB3 ebook (E) are both container files (signed or unsigned ZIP) with metadata and Web-standard contents. One could (in many cases) take contents out of an A and repackage it into an E.
Either one can be the choice for how content is packaged.
