Implement license concurrent model for named users on ArcGIS Online/Portal for ArcGIS

Idea created by jborovanskyarcdata-cz-esridist Employee on Dec 13, 2013

    Example: Consider organization with 300 field workers. They are divided into 6 different ArcGIS Online groups. Each group is tight to specific region, so members of each group should see just one specific region. Only 100 workers can work concurrently at the same time = need to have access to the AGOL (to particular group) and do the same work. Their work is very limited - they need to just display data.
    In such case concurrent license model would be seriously helpful. To have named user for each worker is not very efficient.
