WASTE is a software product and protocol from Nullsoft that enables secure distributed communication for small (on the order of 10-50 nodes) trusted groups of users. It is designed to enable small companies and small teams within larger companies to easily communicate and collaborate in a secure and efficient fashion, independent of physical network topology.
WASTE currently provides the following services: Instant Messaging (with presence); Group Chat; File browsing/searching; File transfer (upload and download). It uses link-level encryption to secure links, and public keys for authentication. This network is built such that all services utilize the network, so firewall issues become moot. It is licensed under the GPL.
