Lionel, Your post reminded me of a VERY old post by Sayamindu Dasgupta: <a href="http://sayamindu.randomink.org/ramblings/">http://sayamindu.randomink.org/ramblings/</a> He talks about doing things with EPUB format to make more interactive books. He doesn't specifically mention JavaScript. What got me thinking is this: <a href="http://www.amazon.com/E-Book-Enlightenment-ebook/dp/B005BYST5I/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1346102690&sr=1-1&keywords=e-book+enlightenment">http://www.amazon.com/E-Book-Enlightenment-ebook/dp/B005BYST5I/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1346102690&sr=1-1&keywords=e-book+enlightenment</a> Check the book cover. It is the Read Activity showing the EPUB of the book "E-Book Enlightenment" being read. Note that the page layout is quite nice and includes fancy dropcaps and art that a Kindle or a Nook would make a mess of or just ignore. So maybe, just maybe, the Read Activity could handle JavaScript in an EPUB as well. If you do "Look inside the book" you'll see that I had to reformat the book to leave out the art and to use a large first letter instead of the much nicer dropcap. The EPUB from <a href="http://archive.org">archive.org</a> has the original formatting. So maybe instead of making custom wrappers for Activities that use HTML 5 and JS we could make non-standard EPUBs and accomplish much the same thing.

Project Gutenberg makes EPUBs by taking the hand crafted web page and putting it in a Zip file with some XML files. On Read it looks just like the original web page. On a Kindle it might look just awful. I don't know if the ENYO framework is entirely JavaScript (in which case it could be included in the EPUB) or if it has some non-JS portions. It sounded to me like it did. Those portions would need to be added to Read.

Since Read uses WebKit it already renders EPUB books created from web pages (like those from Project Gutenberg) better than Nooks and Kindles do, and having some JavaScript on the pages would be a natural thing to experiment with.
