You touch on an interesting concept, making a congestion algorithm which is fully tunable. Maybe then the job of calculating the optimal tunables could be moved out to a daemon which does Remy-like simulations to keep the algorithm in optimal state. Obviously we don't yet have the compute power to do that as effectively as Remy in real-time.
