The key of this sample is that AMFChannel is defined by AS3.

This is awesome! Many thanks for posting this. I was banging my head against a wall until I saw this.

Yeah same here! Thanks! This is a great example and its greatly appreciated. I haven't yet tried this but I have been using Consumer and Producer in Flex along with CF8 and I've found it so easy but I've always wondered how is it doable in an AIR application. Thanks for sharing Shigeru! But just to point out I don't believe you need to call sendGatewayMessage in the onIncomingMessage function. Simply cfreturn the struct you've created and all subscribed clients should receive the message.
