You can now view 3dmodels in google 3d model maps using the Google Earth Plugin.
To see this in action, first find a geo-referenced model in the Google 3D Warehouse. Then, click on the Map tab and choose the Earth
map type (this plugin is currently only available on Windows). You'll
see the model load and the view change to focus on the 3D model - all
within the 3D Warehouse.
