Note: The functionality offered by the XS software is maturing quickly and interacts deeply with the XO laptop software. Some of the features listed below work in a limited fashion and may only work completely with the latest XO software.

  • If an Internet connection is available, acts as an Internet gateway, providing access to the Internet to the XO laptops.
    • Includes an HTTP proxy, saving significant bandwidth and providing faster access.
    • Can route the Internet traffic through a content filter controlled by the Ministry of Education or other relevant agent.
  • Supports various wireless network setups, including standard Access Points.
