Automate Bing Maps KML Export

We need an application that will automate the exporting of mappoints in Bing maps. It needs to name the category it is saving. For example, if a map is saved under category restaurants, it needs to be saved as restaurants.kml. It needs to be automated, so that when you open it everything is automatically saved. The application should have a configuration for login information and save locations. The application needs to save in a subfolder and not overwrite itself. The folder should be named as the time it ran.
