I am part of the community over at http://forum.xprize.org/ which I joined to discuss the Global Learning X-Prize and other breakthrough technologies with other interested people.
The prize is a competition to create (primarily off-line) software to teach basic literacy skills.
The topic of your project recently came up and a degree of scepticism was expressed from some quarters.
The X-prize community contains many influential change-makers from around the world and, especially as you are in the process of raising money, I thought it would be a good idea to extend to you an opportunity to address these concerns directly.
For my part, I think the project as described could potentially be very valuable. I suppose the big question I have is - will you really, actually, truly be able to build lantern and turn it on at 2MB/day if you get the money, or is it just a gimmick to attract attention to the wider project?
