EPUB3 is based on the XML serialization of HTML5+CSS (<http://idpf.org/epub/30/spec/epub30-overview.html>) and as such uses the same UA's (especially WebKit-based ones).   In addition, because it is simply a packaging of (X)HTML5 plus associated resources, it can indeed be placed on a server and transparency served up.

EPUB is not HTML, so it does not get interpreted by a HTML UA and
therefore not exposed through the HTML IDL. Even if there is HTML
somewhere in EPUB, you are not delivering a HTML file to the Web
browser but an EPUB file. If you want to interpret EPUB markup in a
Web browser you need a plugin.
