One of the critical value components to the Operations Dashboard for ArcGIS is the ability to track events in real time. In order to continue to be relevant with regards to real-time data tracking and management, Operations Dashboard must support Stream Services and Stream Layers. Even if supporting widgets and data feeds from a stream layer is difficult, Ops Dashboard should at least allow a user to pull in a Stream Service/Layer as a visual reference, just like you can do in a web map.
