I would like create a maps-app (virtualEarth or Gmap) and have to generate various pushpins/markers at runtime from database.Also there should be a way clustering(like http://www.soulsolutions.com.au/Default.aspx?tabid=103) all the markers on server-side for performance reasons.Is there a way to generate pushpins/markers on server an pass this to view or is there any other good idea to solve such problems.I'm deeply grateful for some comments/suggestions
