The New York State-Local Internet Gateway Prototype project represents goals and challenges of vital interest to every state and to any other federated system of government. The findings and lessons reveal the importance of understanding and balancing the goals of data and service integration against the related challenges of complexity and cost. Thanks to the contributions of many experts across the intergovernmental landscape, these project results should be of value in New York State and in the many other governments that are attempting to strike that balance.
