I would have thought this would come in very useful for business.

...it's now possible for you to build your own Street View experiences to do just that. Using a new feature in our Views community, you can easily connect your photo spheres to create 360º virtual tours of the places you love, then share them with the world on Google Maps.Build Your Own Google Street View [google-latlong.blogspot.com]

To get started, just create photo spheres using your Android phone or a DSLR and then share them on Views. Next, select the photo spheres from your profile and use our new tool to connect them together (as seen in the example above). Once your photo spheres are connected and published, people can navigate between them on Google Maps, just like they can in Street View.
