NitroShare is a network file-sharing application that makes sending a file to another machine on the local network as easy as dragging-and-dropping.
OpenAG is the first Unix/Linux/Mac OS X implementation of the (unofficial) Audiogalaxy File Sharing Protocol. OpenAG includes both client and server projects. The client is available as a command line application or with a Mac OS X Aqua interface.
P4 is a fully functional, self-organizing overlay network similar to Gnutella and Freenet. However, P4 differs in that it provides an API for developing plugin applications on top of the network. P4 handles the networking and exports functionality for unicast, multicast, user and plugin discovery, and strong encryption and authentication. This frees developers from worrying about networking, and allows them to focus on building real functionality.
An all-in-one software solution for P2P networks. The software consists of two components, the P42 Client and the P42 Development Kit. The client is the core of the software package and has a special pluggable architecture.
Pods is a P2P network, but more generalised than existing ones like Freenet and gnutella.
