First let me tell you that I think you are terrific. We both know that few people really understand what you are doing but I know it will help my mission to establish Peace on Earth by 2027. Part of what I am doing involves universal education.
I googled OLPC and Arlington and one of the choices landed me here. You will find, if you decide to work with me, that I have a very open mind. If you can tell me your idea I can probably break it down to the LCD and tell you where to start.
The remainder of people who need to be educated at least to read, write, and do basic math fall into 3 groups. Poor, remote, disabled and/or otherwise challenged making them a poor candidate for traditional classrooms.
I need to set up a Beta program, I would like it to be run through Arlington Public School, to be able to film actual children and their progress with the online educational process. Adding the mapping element you are working on will give the children of the world a better feel of where their new age pen pals live at.
