Galet is a peer-to-peer application which primarily aims to provide easy-to-setup, secure communication channels between the computers of people who know and trust each other. Its secondary goal is to create a public network based on these channels. No direct connections occur between two nodes that have not been explicitly accepted by the users of these nodes. This makes the network very difficult to censor, as an attacker's direct access to the network is limited.
G-Serve is a file serving bot for people who wish to share files on IRC. It does not require any other IRC chat program to run and has most of the usual f-serve features such as searches using @find and send queues. It runs as a daemon and maintains logs of connections and transfers.
