I just ran into this for end-to-end Scrum management that runs on top .  Pretty nice for those of you out there doing (or trying to do) Scrum and have adopted TFS.  Here's the info from the download page:

eScrum is a Web-based, end-to-end project management tool for Scrum built on the Microsoft Visual Studio Team Foundation Server platform. It provides multiple ways to interact with your Scrum project: eScrum Web-based UI, Team Explorer, and Excel or Project, via Team Foundation Office Integration. In addition, it provides a single place for all Scrum artifacts such as product backlog, sprint backlog, task management, retrospective, and reports with built-in context sensitive help.

Please note that eScrum requires TFS to be installed.
