"cryptic6 is an encrypted P2P protocol based on ideas from Virtual Private Networks and Stanley Milgram's essays on 6 Degrees of Separation. VPNs, such as WASTE, though exceptionally secure, are missing the most popular feature of other P2P programs, that is connecting to people you don't personally know. cryptic6 would allow you to connect to untrusted nodes through mutually trusted nodes. Two parties would not usually separated by more than six degrees. The network would have some similarity to WASTE, using public key encryption to connect directly to all trusted nodes, but would have the advantage of connecting to the larger network by proxying though chains of nodes.

Currently we are writing it in Python, and using the Twisted implementaion of ssh."

"MobileMule is a small subproject of eMule, which let's you control your eMule with any java-enabled mobile phone (actually not any, but most). Note that MobileMule is NOT a eMule for your mobile phone, but a remote control for your eMule."

"Quack is a headless gnutella server, intended to be run unattended (i.e. in "daemon mode"). Most gnutella servers only allow searching based on matches to the filenames of the files being shared. Quack allows an external index file to be used in addition to matches on the filenames. This allows the user better control over which files will be matched.

Quack is written in python, and should run on any platform supporting python, sockets, and select. It has been tested on linux."

"Turtle is a new tool for facilitating free speech by combining encryption with peer-to-peer (P2P) technology. Turtle users can exchange information deemed ``controversial'' or ``risky'' (for example whistleblowers exposing government or corporate abuse) without being exposed to legal or economic pressure from parties that may want to censor or suppress this information. Such users are likely to be found in countries where the government routinely snoops on citizens' communications. It will also be attractive to people in all countries who value their privacy.

Technically, Turtle is a friend-to-friend (F2F) network - a special type of peer-to-peer network in which all your communication goes only to your friends, and then to their friends, and so on, to the ultimate destination.

The basic idea behind Turtle is to build a P2P overlay on top of pre-existing trust relationships among Turtle users. Each user acts as node in the overlay by running a copy of the Turtle client software. Unlike existing P2P networks, Turtle does not allow arbitrary nodes to connect and exchange information. Instead, each user establishes secure and authenticated channels with a limited number of other nodes controlled by people he or she trusts (friends). In the Turtle overlay, both queries and results move hop by hop; the net result is that information is only exchanged between people that trust each other and is always encrypted. Consequently, a snooper or adversary has no way to determine who is requesting/providing information, and what that information is. Given this design, a Turtle network offers a number of useful security properties, such as confined damage in case of node compromise, and resilience against denial of service attacks (for more details on this see the Documents section)."
