We (the dev team behind Channel 9, Channel 10, Mix Online, and others)been doing scrum-ish development for a few sprints now, but we recently switched to using eScrum. This is a set of templates and tools for use with Team Foundation Server and it really rocks. There are few less-than-polished elements about the install and the web interface, but I’m glad they shipped it out for general use.

You can read a good summary of eScrum on the blog ‘A Developer’s Life’, which is also a good resource for lots of other Visual Studio related news.
