Before revision:  This work is strongly motivated by emerging applications in flow level performance of wireless networks that give rise in queueing models with scalable service capacity, such as the discrete-time processor sharing queue with limited state dependency, as well as in queue-based random access protocols, where the network's parameters are functions of the queue lengths.
