I totally agree that these other areas are super-important. At first I thought you'd be suggesting that I created areas for them on the intranet, like the Planet.Intra demo site linked from the dotWRK home page.
But then I realized that you're actually asking for functionality and integration. That's cool, but would obviously require some funding to get implemented. I've added it to the mock-up, so it can properly serve as a product vision.
I've added the items you mention but I'm not sure about the structure that's there right now.
