If you're interested in what the new Groove CD-Packages probably will look like: Check out this link i just dug up.
Another screenshot of the CADviewer under development by Tim . Nice new buttons :-) I like the drawingspace concept more and more the longer i think about it.
Technology prediction by Ray Ozzie in this article: "If we continue on the current trajectory, e-mail will become the place where you receive stuff from people you don't know, and Groove and other collaborative environments will be where you work with people you know."
