I think you are correct mrshoe (regarding the "can we" vs. "should we" and also about using the best interface for a given purpose.) We developed an app very similar to this (restaurant ratings, school ratings, vacant apartments, homes for sale, home sale prices, traffic flow visualizations, etc. etc.) for our real estate brokerage and real estate investment division. It got a nice "gee whiz" response from some of our geekier clients, but that was about it. We stopped using it on phones when our first client nearly broke their leg by tripping on a curb. [We don't like lawsuits.] We now use a multitouch tablet instead. The picture quality is much improved, clients can use gestures to manipulate the data, and they don't run into things anymore.We just call them 'interactive maps' so we don't scare our less tech-savvy clients. This type of thing has been around for awhile. I don't completely understand the novelty this holds for this particular (techy) crowd. I guess the future is still just really unevenly distributed...?
