AdWords Ads on Google Maps

ClickZ has reported the appearance of AdWords ads on Google Maps. To quote from the article:

"Google is experimenting with plotting local advertisers' locations on its Maps product, giving marketers a visual and spatial accompaniment to their locally targeted ads.

A search on "hotels" in New York City returns an organic list of local hotels, plotted on the map with red markers and bracketed by sponsored hotel listings, plotted on the map with blue markers. The same search in other locations, such as San Francisco, doesn't yet return the paid listings."

I can see how this integration of ads, if fully adopted, will be huge for AdWords users that adverise products and services that are location sensitive.
