I think I don't get the point. Real-time collaboration is something we have already (google docs, hackpad, ...). And besides, if it's true that it works only for IE, what's the point?
EDIT: A guy in this thread told it works only for IE, then this statement was fixed in "also works on Chrome". Since I'm a GNU/Linux user I could not verify myself.
