We report on work in progress towards a practical implementation of a software defined overlay network that provides data delivery services at a freely definable and provably optimized quality of service. Our example implementation establishes transparent secure transmission, where security is in terms of confidentiality, authenticity and availability. Using general techniques from game-theory, we show how to simultaneously optimize several performance indicators of a transmission service, taking care of interdependencies and using security as a showcase application.
