It can be done relatively simply when you make direct deals with ad agencies or cross-promotion deals with other product companies. The problem is that no ad network wants to be a part of it; and for the little guy, ad networks are the only thing with economies-of-scale large enough to be interested in purchasing your nearly-worthless ad-space.
Thus my view: we need a "catalogue of creative, you pick what you run"-style ad network, so that the little guys have somewhere to turn instead of acquiescing to the existing networks and ending off with their sites showing chumboxes[1].
