Having done a little bit of work with Flash over the past several weeks there are a couple of things I've discovered as I've worked through some practical examples. There's only really one thing signficant, but a couple of things that you need to be aware of when doing Flash remoting with Zend Framework.

Simple interface? Easy. Useful interface? Just a little harder.

In other words, with a simple architecture it's easy to do. In a more useful architecture there are some things to be aware of.

While I am not a great Flash developer... OK I'm not even a good one, I have been recently been looking at ways of integrating Flash and PHP with the release of Flash Builder 4. I think that PHP is a great way for Flash developers to access their backend systems. This is not because I have anything against any other technologies that a Flash developer might connect with, but instead it is because PHP is a great language to use when another language is your forte.
