Adobe AIR 1.0 has been released and simultaneously released is the 1.0 version of the Aptana plugin for Adobe AIR application development. The plugin release now bundles the Adobe AIR runtime and SDK making it even easier to get started with AIR development. The 1.0 release also comes with Jaxer integration allowing you to develop Adobe AIR applications with generated proxies for your server-side functions. Adobe AIR projects in Aptana Studio can be run against a local Jaxer server during development and then built against the deployed web address of your application during exporting. A screencast demoing this new feature will be available soon on aptana.tv.
I have written an article on the Adobe AIR development using Aptana Studio on the Adobe AIR development connection.
