Hello Mr O'Shea, My name is Edwin van den Oetelaar (some info http://www.linkedin.com/in/oetelaar ) I would be interested in making this work also as a universal display module for my linux appliance. (keys using I2C maybe) It sounds feasible to me, I would expect a maximum of 15 fps, but for me that is OK. Please keep the list updated on your progress.
