Microsoft acquired devBiz and is now offering their TeamPlain product as a free download! TeamPlain Web Access for Team System can be installed on any server running IIS and can allow you a peek into TFS from any platform. At my work, I can see it being especially useful during triage meetings or even our support people.
Give it a spin – it does not disappoint. Word is that Microsoft may release this — or something closely resembling it — with Visual Studio “Orcas”.
