gwt-in-the-aire

Makes the Adobe AIR API available for GWT (using JSNI) and provides a linker to compile Java to JavaScript and produce an AIR application in a single step.

For now, the linker produces an AIR intermediate package (i.e. you later need to sign it using the ADT). I've been able to package the Showcase sample from GWT 1.5. Follow the link in the right pane to try it out.
