No, I understand. "Someone is confused about AirPlay" was more accusatory than I meant. I genuinely don't know if Cabel knows much about AirPlay, I only know what I know from working with it and uPnP/DLNA for the last some months, and it made this seem unlikely to me. He may well know more than I and I learn something new and useful. :)

Based on the anonymous comment in this thread and this tweet, I'm potentially happy to eat my words. https://twitter.com/jmreid/status/306987650001301505
