Nice work Peter. We have an application where certain site specific information is contained within the application scope on the frontend (self contained applications per site) but within the session scope on the backend (an admin application for updating the info of multiple sites), and created an object that would take the scope name to know which scope to apply the structure to. Great solution you worked here.
