Smart Cities as Big Opportunity

In the Cisco Blog.   A pretty common thought.  Consider a city as an internet of many things.  What can be done to improve, enhance and monetize the resulting mega network?  First I have seen numbers to support the effort.  Useful numbers, but I think this will move along incrementally and selectively.  I also rarely see the supply chain aspects of this.   Everyone understand cities need better transportation systems.  They also need that same transportation system to deliver resources effectively.
