WiPeer for Windows

WiPeer enables sharing files directly among computers, playing multi-player games, chatting, and collaboration over both Wi-Fi and home/office networks. These networks are not centralized on a single computer and do not need Internet access.

The only thing you need to enter the network is a username. Then you can start sharing files, chatting or even playing chess, reversi, connect four and checkers. Chat rooms may be public or private, as well as file sharing, which can be done individually or with more than one user simultaneously. Network users can have their own personal profiles including data such as name, location, language, age, sex, etc.
