Andi Gutmans, the CTO of Zend, blogged yesterday about a new proposal making it’s way through the Zend Framework process.
Adobe has made a proposal for an AMF (Action Message Format) component in Zend Framework. This ZF component will allow for client-side applications built with Flex and Adobe AIR to communicate easily and efficiently with PHP on the server-side. Leading the design of the component for Adobe is Wade Arnold. Wade already has a track record of bringing the Adobe RIA technologies to PHP as a result of all of his work on AMFPHP.
I know everybody over on the Zend Framework team is real excited about this proposal. If you work with Zend Framework then you are going to want to keep an eye on it.

I would be willing to wager that your code is not much better than your lexical abilities.
Zend Framework Rocks, and Hats of to Adobe for embracing another corner of the development community and kindly providing support for clean integration of the two platforms. AMF communication for Flash and Flex is now supported on .NET, Java, PHP/ZEND, Python and several others. So what exactly is bad about that? perhaps you would prefer closed source, a distinct lack of integration and vendor tie in?
You wouldnt last long in my team whoever you are.
