The Groove we experienced is mostly about the future, not the present. Groove craves computers and Internet connections superior to today's standards. It is expandable, adaptable, customizable. For that, though, developers are required. Instead of a central server, Groove taps the storage and processing power of individual computers and makes them share.
Groups can set up one or more workspaces without asking busy or reluctant network administrators.
Groove even runs across security firewalls, so you can access Groove from home or the road. There's built-in encryption, so the files should be available only to those you invite. But making promises is the easy part. Some versions of Windows only let network administrators install new software, so it's back to asking their help on that one. That reduces the software's usefulness for home users and travelers.
