JavaScript API for complex cross-multi-site messaging and management
Bring multiple Web site's services together into a single application without having to build complex server-side code, proxies and signed applets. Combine HTML5's cross-site messaging and the ease of use of REST into a single powerful API and you have AppletJAX!
Based on a simple "listener" or "observer" style interface, AppletJAX takes the hassle of managing who's messaging who, who's listening to who, which message belongs to whom and replaces it all with simplicity and elegance.
