Update: Milestone 2 has just been released with preliminary support for the Yahoo! BrowserPlus™ API, and a JsCollections module to ease working with JavaScriptObjects

Makes the Adobe AIR API available for GWT (using JSNI) and provides tools to ease "GWT in Adobe AIR" development:

• a GWT Linker to compile Java to JavaScript and produce an AIR application (or intermediate package) in a single step
• an RMI BrowserManager to run JUnit unit tests within the ADL (AIR Debug Launcher)
• a GWTShell subclass (AIRDebugLauncher) to launch the GWTShell (eventually with the embedded Tomcat) and run the application in the ADL

Given the lack of AIR hosted mode, you'd generally use GWT-in-the-AIR when developping applications targetting both the web and the desktop. Work is under way to build an OOPHM client compatible with GWT trunk (future GWT 2.0).

You'll need GWT 1.5 or later to use GWT-in-the-AIR (GWT 1.6 is not yet supported, as far as tools are concerned)
