I am trying to use AirSquirrels's Reflector to mirror my ipod touch screen to my computer over AirPlay at my workplace (to record screen video). Works fine if I set up a hotspot network, doesn't work if I use the regular network. So I'm guessing blocked by firewall. Is that a common thing among PC-loving IT guys? If I buy a cheap router or Airport express, I should be fine just having that set up even without internet, right? It will send AirPlay over that router and use the existing wifi for internet. If I keep on using the hotspot option, will my mac and ipod touch use the hotspot for internet, or will they still use the real wifi? That's a lot... mainly I just need to know if there is anything wrong with what I'm doing, or better ways to achieve it.
