Has anyone had any experience creating a WiFi network capable of more than 100 simultaneous device connections? Can this be done with non-commercial routers? Can I bridge multiple AirPort Extremes? Suggestions? Recommendations? I realize internet bandwidth will likely be crap... in fact, we don't even need an internet connection for what we want to do... merely have a bunch of devices (mainly iOS) on the same network to test a network based app.
