The RACHEL project, from http://worldpossible.org, provides downloadable content for use offline. Kids on Computers has used some of this content (e.g. offline Khan Academy Video collection) on individual laptops for past projects.
The RACHEL on Raspberry Pi project provides the means to run a server with shared, local content distributed via Wi-Fi or LAN where Internet access is unavailable or limited.
See http://pi.worldpossible.org for more details.

How It Works
- Follow the instructions on http://pi.worldpossible.org to download the RACHEL Pi package, then load the image onto the SD card.
- Insert SD card into the Pi
- Initial start up
- Attach HDMI cable to Pi, and a monitor
- Connect ethernet cable to Pi, and to your home router (needs DHCP address)
- Connect USB keyboard to Pi
- Power up the Pi with micro USB connection
- Update. This will take several minutes, based on your bandwidth.
- (Default username is "pi" and password is "rachel")
- sudo apt-get update
- sudo apt-get upgrade
- sudo shutdown -h now
- Switch to Wi-Fi
- Disconnect ethernet
- Insert USB Wi-Fi adapter
- Disconnect and re-connect micro USB power connection
- Startup takes about 45 seconds
- If you still have HDMI connected, the console should report the Pi's IP address: 192.168.10.1
- If no IP address is shown, look for errors in the console (e.g. unsupported wi-fi adapter)
- The Pi is now acting as a Wi-Fi access point / hotspot and will give out a DHCP address to clients that join the "RPI" network
- Using a laptop, tablet, ipod, or smartphone with Wi-Fi, look for and join the "RPI" wireless network
- Open a browser to http://192.168.10.1
- Browse HTML content (wikipedia and subset of OLPC), PDFs, and HTML5 video
- If your browser is HTML5 compliant, the video content should work
- There are a few parts of the content that appear to require Flash (?)
