Dirmi is replacement for Java RMI which supports bidirectional remote objects and many more features, including:

• Asynchronous methods
• Remote call timeouts
• Customizable remote exceptions
• Callbacks
• Streams
• Completion queues
• Batched methods
• Disposable objects
• Closeable sessions
• Thread pool constraints
• Custom class loaders

Dirmi is designed for high performance, and it exceeds the performance of Java RMI. Unlike RMI, Dirmi does not have any firewall restrictions. Only one port needs to be opened for accepting sockets, and both client and server can export remote objects through it.
