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.

SlimPeer project client is a fully PeerCast compatible but small, fast, and easy to use peer that can be used for replaying peercast:// streams without the need to perform complex and difficult configurations.

After installation, all PeerCast P2P streams can be replayed immediately.

SlimPeer was forked from the PeerCast sources and is licensed under the GPL. The client (=ui) part of the applications has been modified to be as simple as possible. The core library sources are identically to the original ones but they have been extended by several USE_SLIMPEER switches that disable code that is not necessary for this client (like the configuration via webpage, streaming of own sources and others).

p2pshaper is a Linux QoS script to ensure good latency and fairness on a slow network connection overloaded by p2p applications. It also includes generic optimizations to improve fairness. This release includes a large number of improvements since the 1.3 test release.
In short p2pshaper is a set of scripts for the Linux OS, that is used to administer bandwidth on a network overloaded by massive p2p traffic.
Normally, the amount of peer-to-peer traffic on such networks, will make it impossible to surf, not to mention doing interactive traffic (ssh). The normal action is to shut down p2p traffic totally, and set up the net, so that Internet connection is only possible through a proxy. This breaks many useful programs. And not all p2p traffic is evil. Normally, one would mark packets coming to a specific port (emule ports) to be of a lower priority than packets to other ports. This used to be a good solution. But now, there exist a huge number of p2p clients, eact with different port ranges, and also, some programs are able to change the ports. Normally the Internet newsgroup port should have a high priority. But binary newsgroups are sometimes used for massive downloads, which will use up all bandwidth. Better packet markers are needed.
p2pshaper currently exists in two versions p2pshaper v1 and p2pshaper v2. They both works in different ways, so v2 is not "better" than v1. Which one you use depends on what kind of functonality you want.
Enhancements:
- Added unified patches against recent kernels With the amount of patches p2pshaper needs, people have had problems patching kernels. To make this easier, p2pshaper now includes patches for most recent kernels. This will probably ease the installation of
- p2pshaper. Old patches have been moved to the old/ directory.
- Normal connections will never get into the lowest priority bandIntroduced already in the 1.4.1 release. This makes sure that normal traffic isnt nuked all the way into oblivion, where only evil traffic (marked by l7_filter, ipp2p or band8ports) should be.

bluebery is an easy-to-use SQL/PHP based content manager that provides PHP libraries and methods to use in your sites pages. These methods can be used to easily access and print desired items or an iteration of items that are stored through the bluebery Web UI.
The project includes a library framework for PHP-based Web applications and pages. bluebery can be set up very quickly, needs almost no configuration, and makes writing dynamic peer-based pages very easy.
Enhancements:
- A major bug was fixed in many bluebery files (caused by whitespaces behind the license g*).
- This prevented the previous release from running with authentication.
- It was the cause of error messages which stated "headers already sent by...".
- The doProtection function was added to the library, which performs an include verification and prints out a message in case the file is not included by the authorization file.

Speextalk is a simple, yet powerful voice-over-IP (VoIP) program with a custom protocol using the Speex codec.
The keyword is simple: Speextalk does VoIP, and only VoIP, but the protocol is simple, the code is simple, and the usage is simple for an average Unix user.
Main features:
- Direct peer to peer two persons discussion.
- Low to very low bandwidth usage (can be less than 1.2ko/s).
- Identification of the callee by its IP address or host name and optionaly port number.
- Network protocol independant code (IPv6 is supported, IPv8 would be).
- Text mode interface.
Enhancements:
- Initial ChangeLog creation. Supported features: ALSA sound output, text-mode interface, Speex mono low, wide and ultra-wide band.

BioCluster is a peer-to-peer clustering platform for Asterisk, the open source PBX, which allows Asterisk to be used as a full carrier-grade telephony solution. This project is meant to be installed on several machines together with Asterisk, turning them into a VoIP cluster.

While the BioCluster peer-to-peer protocol was initially designed to cater to Asterisk-based clustering solutions, the BioCluster framework is capable of being extended to support various forms of normally unclustered devices or software packages.
