WASTE is a software product and protocol that enables secure distributed communication for small (on the order of 10-50 nodes) trusted groups of users. Only less then 24 hours after being /.'d it's been yanked from Nullsoft's site, fortunately there is a mirror. Since I'm not sure how long that will last, here's another one. Oh, and there's already a Linux port.

WASTE 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.
Some bits of information about WASTE:
- WASTE is currently available for 32-bit Windows operating systems, and as a limited functionality server for FreeBSD and MacOS X. Porting to other operating systems should be a breeze, as the source is provided (and the network code itself is pretty portable).
- WASTE is licensed under the GPL.
- WASTE currently provides the following services:
- Instant Messaging (with presence)
- Group Chat
- File browsing/searching
- File transfer (upload and download)
- Network architecture: WASTE uses a distributed architecture that allows for nodes to connect in a partial mesh type network. Nodes on the network can broadcast and route traffic. Nodes that are not publicly accessible or on slow links can choose not to route traffic. This network is built such that all services utilize the network, so firewall issues become moot. more information.
- Security: WASTE uses link-level encryption to secure links, and public keys for authentication. RSA is used for session key exchange and authentication, and the links are encrypted using Blowfish in PCBC mode. The automatic key distribution security model is very primitive at the moment, and may not lend itself well to some social situations. more information.
