eldavojohn writes "The developers of software for the One Laptop Per Child (OLPC) initiative are redefining security for the personal PC. Since the laptops have the potential of communicating with any other laptop, the developers have a unique opportunity to implement both virus protection on the kernel, master boot record and also the way in which the laptops deal with security and 'code-sharing.' The developers are currently seeking outside counsel from security experts and if you're worried about these security schemes posing only problems to the children, 'these security measures can be turned off by the PCs' owners. To protect against that leading to disaster, the laptops will automatically back up their data up on a server whenever the machines get in wireless range of the children's school. If a child loses data, the files can be restored by bringing the laptop within wireless range of the server.'"
