Along with the "What?" question, which I think quickhand has now answered, there is also a "Why?" question whose answer goes beyond just the functionality OpenInkpot does and could add to an e-reader device. This thread prompted me to upload an e-reader formatted version of
"Free Software, Free Society". In this book the ideals and reasons behind the Free Software movement and projects like OpenInkpot explained and argued for.
As an aside: Thanks OIers! And keep up the great work!
