Everybody in Local Search is trying to understand that - it's a discussion better held in our Local Search Forum [webmasterworld.com].

The kind of SERP we're talking about here Google has called a blend of organic and local. For example, the listing may be the organic one but enhanced with a map marker or Place information.
