AGX Online is a great tool, and we use it for rapid prototyping. A lot of these prototypes end up having long shelf lives - it's often good enough for the customer that we don't have to go into the Flex development environment. Good job, ESRI. However, not everyone lives or works in a world described in Lat/Long, particularly in the Engineering disciplines in the US. I'd love to see AGX Online offer user selectable coordinate systems, particularly from the US State Plane library. This would go a LONG way towards improving functionality. Thanks!
