VPPPN stands for virtual peer-to-peer private networking. The project provides a VPN client using a custom protocol to be able to set up a point-to-point dynamic virtual network. This differs from OpenVPN in that it does not need a central server to pass the network's traffic. A central server exists to allocate IP addresses and provide a point of contact for the clients, but once connections are established, these services are no longer needed. This means that a VPPN network is free (as in beer), since to set up a network you do not need to invest in an always-on Internet server. Once established, a VPPPN network behaves in a similar way to a normal IP network. To the end user, this means you can set up an office network and drag and drop files between computers in a secure manner over the Internet.
New Internet is an all-purpose resilient serverless network system that overcomes the distinction between "server" and "client" and extends the idea of peer-to-peer networking to any kind of application or service. It implements a growing set of protocols and could be used for direct file transfer or as a serverless mail network.
YML is a research project that aims to provide tools for using global computing middleware such as GRID, peer to peer, and metacomputing environments. The YML software architecture enables the definition of parallel applications, independently of the underlying middleware used. Parallel applications are defined using a workflow language called YvetteML.
