ArcGIS Engine provides an extremely powerful and flexible runtime that allows its users to create some complicated and robust applications. However, for some applications and use cases, the entire Engine Footprint is not needed. The entire runtime install is almost 700 megabytes, which is fairly large if the application is not doing much. By reducing the footprint we could provide a deployment of engine that is smaller, and that would install faster. What kind of applications would you create and what kind of functionality are you looking for is a slimmed down application?
