The company Earthmine have developed a fascinating product similar to Streetview. It will however be used for other purposes and most likely will not be available for free to the public.
Architects, insurance companies and real estate companies for instance will like the built in feature to measure the volume of buildings. Earthmines product is not yet available but it was recently shown at the Demofall Conference in San Diego. The image data is gathered in a similar way as Mapjack and Google Streetview using GPS locators and lots of cameras mounted on top of a car.
You can see a demo of the product here:
