If you are a daily user of Team Foundation Server, I am sure you know the great TFS Power Tools that are released regularly by the product team. The latest version includes integration of Office Communicator Server in the Team Explorer. Check out the screenshot below: There is a new node in the Team Project tree that says Team Members, in which you can see groups and users that have access to a team project. Since I am logged in to Office Communicator, I can see the same availability indicators. When I right-click on a team member, I can have a video conversation or start a VOIP call and all other options that OCS offers. Great stuff!

Update: An entire community has started developing and sharing ideas around Team Members. The Skype extension sounds great. http://blogs.msdn.com/bharry/archive/2008/11/13/extending-the-new-tfs-team-members-power-tool.aspx
