Update for the popular Peer 2 Peer client DC + + (Direct Connect).
This Peer 2 Peer system has earned great popularity in the LAN, virtually replacing themselves FTP- servers. Over the last 2-3 years I have not met a local area network, which would not have been developed DC- community. It can be said that for the exchange of files on LAN it is the best way to do so, and perhaps the only real choice. DC + + is rich and popular in the global network. Thousands and thousands of users vary in different files, including Russian-speaking hub. For a list, please visit hublist.org.
This P2P network works on the principle of universal access to resources. Each user is allocated a number of files that want to share with the society.
