I'm attempting this (360 video street-view) for Buenos Aires.

It is certainly feasible but there are many factors involved, starting from the right lens to dealing with the bureaucracy when trying to acquire permits.

Storage is an issue. A couple of city blocks means a few GB without compression. Since I'm shooting for high quality, I need a better solution than a measly notebook.

Of course, I'm just a mere mortal without an appropriate income for this stuff. Google could do this in their sleep.

Google's shown something like this off before. Video at http://techcrunch.com/2009/12/07/google-liquid-galaxy/

Peugeot currently has a site (Peugeot car promo) that does this: http://www.rczview.com/

Any other sites?
