Last time I looked into this (which was a few months ago) it still wasn't possible to do so but I just found out that you can now embed flipbooks which you create with issuu into other domains! Gave it a try just now and as you can see above it works beautifully!
So, all you need to do is create a free account with issuu, make your flipbook by following the instructions on the site which involve combining the images of your left/right pages into a pdf which you then upload into your issuu library. Once the book has been crunched by the system it will be published, at which point you will find the embed icon (looks like this < >) under the thumbnail of the book. Make sure you have all the correct things checked on the menu which appears when you click on the tags (such as having the double page view as default!), then copy and paste everything into the HTML tab of the post editor and you are done! You can also change the height and width of whatever appears on your blog by playing with the values inside the embed code. If you do so remember to use a calculator so that the aspect ratio remains correct.
Tip: When you publish this there will be several text links which appear under the small flipbook on your site. If (like me) you do not want these text links simply delete the bottom part of the code, which will look something like this:
<div style="text-align: left; width: 420px;"><a href="http://issuu.com/elifayiter/docs/ctrl_xyv?mode=embed&viewMode=presentation&layout=http%3A%2F%2Fskin.issuu.com%2Fv%2Flight%2Flayout.xml&showFlipBtn=true" target="_blank">Open publication</a> - Free <a href="http://issuu.com/" target="_blank">publishing</a> - <a href="http://issuu.com/search?q=computer" target="_blank">More computer</a></div>
