Hidden iOS 6.1 gem: Bluetooth airplay

Did you have wifi on?
I'm going to take a wild guess that it can now use bluetooth to find the apple TV that has airplay, but then will make a direct connection to it using wifi. I can't imagine bluetooth having the needed bandwidth/speed for airplay content.
Edit: Just tried it myself. iPhone on 7.1, Apple TV on 6.1, both with wifi and bluetooth on but neither connected to a wifi network. Airplay didn't work. As soon as both were connected to the same network Airplay started working again.

Did some more tinkering around...
Created 2 separate networks, each with their own wifi SSID. Physically separate LANs both with internet access.
Connected Apple TV to LAN1, iPhone to LAN2, bluetooth on, and Airplay does not show up on the iPhone at all.

Each network still needs to be able to communicate with the other. The purpose for this new feature is that on large networks, it's often the case that Bonjour discovery doesn't work across the subnets, particularly from a wired network to the wireless network but IP traffic is routed between them.
It's in these instances where this new functionality works. Bluetooth identifies the ATV, and then once the two devices share connection information, the Airplay stream moves via IP.
That's what I was thinking about. I found this article while looking around:
http://gadgets.ndtv.com/tv/news/app...tion-discovery-over-bluetooth-and-more-494249
It mentions
In the same setup, I connected the two LANs, but they each had their own subnets. Once doing that, an iPhone on LAN 1 was able to see all the apple TVs on LAN 2, regardless of whether the apple TV was on 6.1 or 6.0.
Sounds like it does make sense though about using bluetooth for discovery when multicast or bonjour is blocked but that there still is IP connectivity between the two.
I wouldn't mind trying to emulate that to see how it works, but I don't have the time and energy right now lol.
Actually it would have been nice if this feature was to allow discovery and transmission for iOS devices and Apple TVs that are isolated from any network.
May be a bit OT - does Airplay work with a guest wifi network (i.e. setup up a second wifi network on your AEBS/TC that only allows access to the web)? I haven't enabled my guest network as several guests like to airplay from their phones to my ATV.
AFAIK the guest network is a separate LAN segment. That's the whole idea - fully isolate guests from your home LAN and just provide them with Internet connectivity.
AirPlay works only on a single LAN segment.
It would work if you also registered your aTV on guest network.
