The ArcGIS Extension for the Google Maps API (http://help.arcgis.com/en/webapi/javascript/gmaps/index.html) provides some wonderful literature how to build-up the mashup scripts. However, some of the samples provided in that website do not work properly if its script is deployed locally. Some professional point out that it may be due to the need for the Google Maps API Premier License (http://www.google.com/enterprise/earthmaps/maps.html). How can a programmer know which script needs such a license or not? The article at http://code.google.com/apis/maps/documentation/premier/guide.html#WhyPremier briefly introduces the Google Maps API Premier License. However, I still wonder how to use the Premier License in the deployment. If anyone knows, please share. Thanks.
