VidinateVärk: EtherPad

Introducing text:
"EtherPad is the only web-based word processor that allows people to work together in really real-time."

and even more:
"When multiple people edit the same document simultaneously, any changes are instantly reflected on everyone's screen. The result is a new and productive way to collaborate on text documents, useful for meeting notes, drafting sessions, education, team programming, and more."
