You know about Google AdSense AdLinks, Gary Price at SEW seems to have spotted cool Yahoo! like AdLinks. These Sponsored Results do not seem to be part of the Yahoo! Publisher Network program, but rather they are hosted on pages, at the Yahoo! domain. At least we haven't seen it anywhere else.
To see this in action, go to the Good Night, And Good Luck movie at Yahoo! movies. Then scroll down to the bottom of the page and click on one of the "Sponsored Links". It will open up as if it was done in DHTML, whereas AdLinks takes you to a different page.
Gary has screen captures, if you do not see it.
I posted a thread at Search Engine Watch Forums.
