Freenet software lets you publish and obtain information on the Internet without fear of censorship. To achieve this freedom, the network is entirely decentralized and publishers and consumers of information are anonymous. Without anonymity there can never be true freedom of speech, and without decentralization the network will be vulnerable to attack.
Communications by Freenet nodes are encrypted and are "routed-through" other nodes to make it extremely difficult to determine who is requesting the information and what its content is.
Users contribute to the network by giving bandwidth and a portion of their hard drive (called the "data store") for storing files. Unlike other peer-to-peer file sharing networks, Freenet does not let the user control what is stored in the data store. Instead, files are kept or deleted depending on how popular they are, with the least popular being discarded to make way for newer or more popular content. Files in the data store are encrypted to reduce the likelihood of prosecution by persons wishing to censor Freenet content.
The network can be used in a number of different ways and isnt restricted to just sharing files like other peer-to-peer networks. It acts more like an Internet within an Internet. For example Freenet can be used for:
Publishing websites or freesites
Communicating via message boards
Content distribution
Unlike many cutting edge projects, Freenet long ago escaped the science lab, it has been downloaded by over 2 million users since the project started, and it is used for the distribution of censored information all over the world including countries such as China and the Middle East.
Ideas and concepts pioneered in Freenet have had a significant impact in the academic world. Our 2000 paper "Freenet: A Distributed Anonymous Information Storage and Retrieval System" was the most cited computer science paper of 2000 according to Citeseer, and Freenet has also inspired papers in the worlds of law and philosophy. Ian Clarke, Freenets creator and project coordinator, was selected as one of the top 100 innovators of 2003 by MITs Technology Review magazine.
Enhancements:
- This release operates over UDP rather than TCP.
- It can transparently operate through firewalls.
- The core architecture and algorithm have been redesigned for simplicity and efficiency.
- A new and even simpler API allowing the rapid development of third party software that interacts with Freenet has been added.

SopCast is a simple, free way to broadcast video and audio or watch the video and listen to radio on the Internet. Adopting P2P(Peer-to-Peer) technology, It is very efficient and easy to use.
Let anyone become a broadcaster without the costs of a powerful server and vast bandwidth. You can build your own TV stations comparable with large commercial sites with minimal resources.
With SopCast, you can serve 10,000 online users with a PC and a home broadband connection
Main features:
- Get stream data from many nodes on the SOP network at the same time(P2P transfer), make the channel more available and stable.
- Build your own channels and broadcast it over the Internet.
- Streaming many stream file types, asf, wmv, rm, rmvb. etc.
- Support for loop file playing.
- A build-in TV station retransmit the channels from other stream media servers.
- Support for many stream network transfer protocol. mms, rtsp, http etc.
- Monitor broadcast source quality and channel quality to help audiences to select a appropriate channel.
- Record the clips when you are watching it.
- Total memory cache, no harm to the harddisk.
- Support for authentication on both the broadcaster and the audiences.
- Support multiple channels broadcast on the same server.
- Small green software, no registry change, no system file change.
- Support URL visit. You can place your URL in your website and the others can earier to view your media.

Futurosoft Ares Plugin for Apollon is a plugin for giFT (apollon) that connects to the Ares peer-to-peer filesharing network.

This file is for Ubuntu, Kubuntu and other distro based in debian.

PeerProtect is an addon for Jays firewall that generates a file which contains all IP addresses from the RIAA and MPAA, etc. and will protect peer-to-peer programs from them. The Database can be copied from PEERGUARDIAN or IPPREFIX.

Dijjer is a peer-to-peer HTTP cache, designed to allow the distribution of large files from Web servers while virtually eliminating the bandwidth cost to the files publisher.

Dijjer project is designed to be simple, elegant, and to cleanly integrate with existing applications where possible. Dijjer uses "UDP hole punching" to allow it to operate from behind firewalls without any need for manual reconfiguration.

Dijjers distributed and scalable content distribution algorithm is inspired by Freenet.

Peers is a distributed programming toolkit designed for building peer-to-peer systems. The toolkit is a hybrid language project which offers low level primitives for managing concurrency and communication.
Using these primitives, complex P2P protocols and complete systems can be designed and implemented in Python, while maintaining high performance for critical operations.
Enhancements:
- [python] Fixed the exceptions. Now peers exceptions have native python exception representation
- [python] Fixes in the peers-python reference count binding for python-land pointers entering the peers kernel
- [python] Fixed bind/unbind for local objects. bind/unbind are now instance methods that can be normally called.
- [python] Eliminated copying in the python representation of x_data
- [python] Added marshalling support
- [python] Fixed old-style class support in multi-methods
- [rpcc] Eliminated conditions of conflicting type regisration in generated Boost bindings
- [rpcc] Makefile/rule file generation scripts
- [rpcc] python-land marshalling support for XX structs
- [cxx] Added support for GNU libg++ atomic reference counts
- [cxx] Removed the immediate dispatch of remote call returns in the event loop, as it can violate logical ordering if back-calls are performed in the same context.
