Considering Yahoo's control of the patent on keyword advertising it would make sense that they would team up. However, I doubt seriously that Yahoo would integrate MSN's search. More likely it would be as an advertising play.

Overall, though, I do not see what Yahoo would get out of this unless MSN gave up search! Now that would be interesting and would really create some buzz if it came to that. May also catch the attention of anti-trust folks.
