Hi! I'm Mark Roest, and I am working with Earth Treasury, whose vision is the end of poverty through communication and sustainable commerce. We are focused on realizing (and maximizing) the potential of OLPC, with four projects in the formative stages. The first is creating a program that is similar to Give One Get One. The second is creating curricula for the XO, especially in collaborative discovery, science and business. The third is supporting the pairing of schools in developed and developing countries to facilitate children going into business. The fourth is using the XO in health care.
