idea: Docs for Teachers

Google Docs uses Gears, an open source browser extension that enables web applications to run offline. When you aren't connected to the Internet, Google Docs uses information stored on your computer's hard drive rather than relying on information sent across the network. When you're offline, your edits are stored on your own computer until you re-connect, at which point your changes are synced with Google Docs' servers and made available to collaborators.
