Google Wave Real-time Document Collaboration

According to news reports, Google has acquired AppJet so that its EtherPad real-time document collaboration tool can be incorporated in Google Wave. I was not impressed with Google Wave's interface and offering EtherPad's fmailar wordprocessor like interface on top will be an improvement. The idea is to allow several eople to edit the same document at the same time and see the changes each other are making in real time. I will be incuding some of this in my new ANU course "Electronic Data Management" (COMP7420).
