Google Maps API: "The Google Maps API lets developers embed Google Maps in their own web pages with JavaScript. You can add overlays to the map (including markers and polylines) and display shadowed "info windows" just like Google Maps."  You need to sign up for an API key (like the search API key), limited to 50,000 page views per day.  Documentation here.  11:57:05 PM
