Overnet was a decentralized peer-to-peer computer network, usually used for sharing large files (e.g., movies and CD images). Overnet implements the Kademlia algorithm. In late 2006, Overnet and all Overnet-owned resources were taken down as a result of legal actions from the RIAA and others. However, since the core of Overnet is decentralized, Overnet clients are still able to function with limited functionality.

The NetFPGA is an open source hardware and software platform designed for research and teaching. Currently there are two platforms: NetFPGA-1G (1G) and the NetFPGA-10G (10G). These platforms allow researchers, and students to build prototypes of high-speed, hardware-accelerated networking systems. As of 2011 the NetFPGA platforms have been used in over 66 academic papers.

Netduino is an open-source electronics prototyping platform based on the .NET Micro Framework. It uses a 32-bit ARM-microcontroller. The Netduino boards (except the Mini and Go) are designed to be pin-compatible with most Arduino shields.[1]
