Update 2014-04-25: This post has been superceded by my new method.
I have a personal server (tolaris.com), a large collection of eBooks, and several Android devices. I like to read books on the go, without the hassle of actually carrying dead trees. But I don’t want to manage local copies of ebooks on my phone or tablet. What I really want is a personal library, accessible anywhere, from which I can download my books at any time. And now I have that.
