What is Microsoft Office Groove?

It comes with Microsoft Office 2007, and I have been trying to try Groove out, although I'm not exactly sure what it is or what it does? It seems like a usefuel tool to share things with people... but if anyone knows what it really does or can provide any help, it would be good :D

its a wierd one to explain but basically its sort of like a peer managment tool which is use by members of business to share files and contact each other.

Microsoft Office Groove is peer-to-peer software targeted at teams with members who are usually off-line or who do not share the same network security clearance. The product was originally developed by Groove Networks of Beverly, Massachusetts until Microsoft's acquisition of Groove
Groove is desktop software designed for the collaboration and communication of the members of small groups. Initially developed by Lotus Notes creator Ray Ozzie (former CEO of Iris Associates), it is a Windows-based shareware. The central Groove paradigm is a set of files to be shared plus some aids for group collaboration which is a shared workspace. A Groove user invites other groove members after creating a workspace. By responding to an invitation the person becomes an active member of that workspace and is sent a copy of the workspace that is installed on their hard disk drive. All data is encrypted both on disk as well as over the network, with each workspace having a unique set of cryptographic keys. Members interact and collaborate in the workspace which is a private virtual location. Henceforth, all changes being made are tracked by Groove and all the copies are synchronized via the network in a peer-to-peer manner, almost instantaneously.

All the members are sent the changes made to the workspace by any of the users and the documents are updated automatically. The change is queued and synchronized to other workspace members, if that member is offline at the time the change is made, but the user's copy is updated when the member comes back online. The change is temporarily stored at the server, if Groove Server is used, which is relayed when the user is back online. Multiple copies are kept for the editors, when more than one person edits a document at the same time, who must agree which changes to save.
