This framework is useful for both open/free and proprietary applications that need distributed computing capabilities. It is capable of being used on almost any Java-equipped platform (JRE/JME 1.2 or higher) (mobile phones, mainframes, servers, embedded devices etc.) It is a “drop-in” framework, because it does not impose any structural requirements or source code changes and is 100% pure Java with no XML code. It also is not dependent on any other frameworks and can work behind NAT, firewalls, even HTTP proxies.
