  • Real-time editing - some kind of Ajax/Comet for server side calls.
  • Version-control.
  • Built in Google Web Toolkit (GWT).
    • GWT involves Java, Javascript, CSS, HTML.
  • Custom built protocol. Wave protocol.
    • Uses the xmmp standard
  • Rich text-editor.
  • Language translation.
  • Google Gears, for drag and drop (of files) functionality. Trying to get it into the HTML5 spec.

The revolutionary part is Operational Transform. Based on the Jupiter collaborative system.

I understand that they use an Extension to the Jabber protocol for the federated wave servers.

The realtime editing is based on an algorithm sometimes called jupiter algorithm and described in this paper. More informations can be found on http://www.waveprotocol.org/whitepapers

It's using HTML5 for the interface and XMPP (Jabber's protocol) for the communication stuff.
