Plotting Zip-Code Boundaries using Ajax.Net and Microsoft Virtual Eart

During a recent project, I had the opportunity to play around with the Virtual Earth Map Control from Microsoft (http://dev.live.com/virtualearth/sdk/). The goal of the project was to display zip codes by outlining its boundary. In the end we decided to go a different route, but I thought I would share the prototype (~200 lines of code including markup).
