Yet again a 'cool wall' nomination! My colleague Peter came with a nice solution to demonstrate Virtual Earth integration with SharePoint lists.
When searching an address with the control web part, the map web part will zoom into the address location, surrounded with other locations (pins) that are stored in a SharePoint list.
The address location coordinates are automatically filled in the list when entering a new location address in the list using an event handler.
It is also possible to use satellite views in the web parts. With a few modifications, it would also be possible to integrate Google earth.
Nice work!
UPDATE: After some warming comments, I've asked Peter to put the Virtual Earth web parts on CodePlex and share them with the community!
