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.
