Correct me if I'm wrong, but don't most of the third party clients already do this? Pidgin, for example, supports both buddy info and buddy icons. If I'm reading the requirements correctly, pidgin, adium, and any other downloaded clients will not be required to incorporate advertising as the individual applications usually don't have more than one or two accounts connected at a time. It is the web clients like meebo that will run into the advertising requirement.
