There already is such a system, supposedly. I've seen it tell me things like I am #4 in queue. I've seen it wait for its turn in queue. Even with a queue system you will still run into jam ups if there are too few nodes and too many users. Think of it like the grocery store on a larger scale. Sure you have 15 cash registers, but if each cash register has to serve 10,000+ people then it becomes a virtual impossibility.
