So I installed TeamPlain on my sandbox to see how it behaved, well let me tell you that this is a cool product. It's all web based and gives you access to your TFS work items, all the reports, your documents on the WSS site and even your source code. You can access those things from either VS or WSS but it's now all in one easily accessible site and it look pretty sweet. Well done guys…
I'll definitely recommend it for specific scenarios. You still need a CAL to use the site (so you can't just install this, and access it without a proper CAL). For manager, Call centers operators (to input bugs) or other offline users it will be great.
You can get TeamPlain from here or follow the link in my links section.
