Callback from Flash

I've been looking into developing a Flex app lately (AIR apps are all the rage these days) and I was wondering how you're integrating Flash with CI. I assume you are using the native AMF binary format with a RemoteObject for the data (especially since you're developing a game). I realize Zend handles AMF natively, but I'm a CI guy. So the only thing that works for me is AMFPHP (http://amfphp.sourceforge.net/). It is free, simple to use, and it works on any PHP server. I'm using it side by side with CI on the server - but if there's a better way to integrate it with CI I'm all ears.
