For me the electronic versus paper thing comes down to what I bought the book for.
For a book that I just need to reference occasionally, epub is usually fine. For a book where I'm starting from scratch, learning new things and coming back to the same bits over and over again, I prefer a paper version that I can write in.

Sounds like a cool project though - good luck!
