Recently came across this really cool project that already has some working, proof of concept code and hardware. It's called The Open Book with goals of being fairly cheap, using decent off the shelf parts, and based on the Arduino platform which is eminently customizable and hackable.
Definitely not ready for prime time for anybody, however anyone interested in tinkering and is good with UI/UX for e-readers could certainly lend a hand in coding/designing the UI for the device, since right now it doesn't have much of one.
