Real Net is an attempt to create a node based autonomous network over an existing WAN or LAN, the main aim being internet applications. The software is designed to run as a low priority daemon on any platform that supports java, and create an accessable "virtual computer" that can be used for distributed data storage, network mapping, and potentially processing.
The network has been designed from the ground up with security in mind, and uses strong public key cryptography. It's distributed nature makes the network extremely fault resistant, and self healing.
