Moonshadow Mobile is making US Census data available on a high performance platform. They have taken the data and geocoded it for Google and Bing maps. The service offering is a proprietary, patent pending system that is able to search through between 20 and 100 million census data records in under a second. Moonshadow has the full census data set, even down to individual voter registration records which only be released to office holders or government entities. The Moonshadow Mobile API offers developers access to a subset of this data.
