Well, it seems that Mr. Aral Balkan doesn’t lose a minute, aside of all the OS ( open source ) Flash Proyects of OSFlash, hes been developing a great proyect SWX wish is a native data format for Flash. It uses SWF files to store and exchange data. It also implements an RPC gateway (currently in PHP), tools (a data analyzer/debugger and a service explorer), various APIs (Flickr, Twitter, etc.), and an ActionScript library that make creating data driven Flash and Flash Lite applications a piece of cake.
If you download and Install the SWX MAMP(Mac – Apache – MySQL – PHP) Bundle (on OS X) click here to download. It will be up an running in no time ( and it’s really like five minutes ). If you already have a development local server You can download the SWX files in zip format( from here ) and extract them on your localhost’s root folder.
Here’s a very neat tutorial that Aral put up on SWX Format site to help you out with the basic steps in how to get it running:
