Khan Academy has introduced a new service called Khan Academy Lite (KA Lite) that acts as a servers to distribute content over wireless LAN, using peer-to-peer sharing techniques. This will allow content on Khan Academy to be available to those that do not have access to the internet. The project has been designed to be compatible across wide-range of systems, and kinds of internet access.
Khan Academy intends to work on developing the system to enable creation a chain of peer-to-peer systems, with just one or few machines with internet access. KA Lite currently works along the same lines, with a central server synching information across clients. The server was originally designed to run-off a laptop; however, the developers discovered that the servers runs quite smoothly even on a Raspberry Pi with a Wi-Fi radio.
