You are doing something great!
This dictionary could be very useful to read anything from Hamlet to Dickens, and many contemporary books too. At least for a French person like me!
I wonder if I can use it with my BeBook (Hanlin clone).
Did you try to get in touch with the guys from the OpenInkpot project? Maybe they could help implement a fast and convenient search feature, like a virtual keyboard, or a way to select a word from a book and look up its definition in a dictionary?
Thank you very much for what you are doing!
