Boing Boing has links to screenshots of Sugar, the desktop interface for the One Laptop Per Child project. It uses wireless ad-hoc networking to build several “views” that allow users to interact with other users on the network. It’s a very innovative and fresh approach to interface design, really integrating social actions into the core of the desktop.
Part of the reason I applied to the School of Information was an interest in mobile ad-hoc networks (commonly called mesh networks) and social issues on those networks. It’ll be interesting to see how the OLPC project deals with issues such as free-riders and free-loaders on the mesh.
