My company wants to use Google/Bing maps to map out our sales territories. I would like a jquery (or silverlight or something) plugin/library that would allow an ordinary user to draw and manipulate shapes on Google or Bing maps to draw out our sales territories. Then I would like to export this information as KML or something similar. I'm looking for functionality similar to http://scribblemaps.com. I've been searching for a while, but haven't come up with anything. I'd rather see if this sort of thing existed before I spend the time to write my own.
