It's called "Product-Tubi-ty" and it's designed for employees who are streaming the free site at work, but don't want their bosses to know. It can be downloaded to a local PC and if "the man" comes by your desk,  it can be instantly triggered to switch to an article about office productivity and freezes the stream in its place until you can get back to it. 

Sneaky, but I'll bet it proves to be popular.
