I hate what Sky have done with Sky Go. Sky Player was great, could have something like 11 devices. Sky Go only allows you to have 2!
My Mac, my roommate's laptop and that's it. What about the Xbox and our iPhones? Only good thing to come out of Sky Go is they let you stream on two devices at once.
Doesn't surprise me Sky won't let AirPlay work on it. No different to me plugging my laptop into someone's telly and using Sky Go. They clearly don't want people using Sky Go as a replacement for the TV package.
