In one of those countless "predictions for the coming year" articles the columnists like to write in late December/early January, PC Week's Rob O'Regan says we'll see a new killer Internet app which will combine instant messaging with "document sharing and other real-time collaboration."

Sounds like a cool idea to me. I'm far from an expert, but I wonder if Jabber's XML-based protocol and the open source model in general will make it possible to turn it into this kind of app. If so, it looks like a great chance to show the world (once again) what open source can do!
