The "network of queues" architecture reminds me of Prof. Matt Welsh's PhD thesis titled SEDA: Staged Event Driven Architecture. It has benefits of both the concurrency offered by event driven and parallelism offered by threaded architectures. http://www.eecs.harvard.edu/~mdw/proj/seda/
Of course, the network of queues isn't the only thing that makes the system possible, but it closely resembles processing in a distributed system; a system of workers.
