A member at Search Engine Watch forum discovered a new test Google is trying out. There is no official name for it yet, but we can nickname it "More Site Results". Basically, you can see from the picture below, that Google is embedding more site results from a page.

This does not appear to be any form of AdWords, and GoogleGuy confirms that "this isn't spyware." In fact, he says this is a UI experiment by Google.
Two things: (1) The members do not like the fact that it pushes down the other results. (2) It seems like Google is able to break out a site by section. Look at the Amazon sample, Google breaks the site up into at least these categories; Baby, Books, Toys & Games, Free e-Cards.
