VSTS Web Access available for download
Awhile ago, Microsoft acquired TeamPlain. TeamPlain provided a web based view of TFS including work items and source control. If you know TFS it is more or less the web equivalent of Team Explorer. Earlier this week, we made available an updated version of this tool. For more information check out the Team System Web Access Page.
Brian Harry's blog post is also very useful.
You can download it from here. I have just downloaded it (3.2MB) and installed. It took less than 10 minutes in total.
