Open Source Network Clients in Java

VPPPN stands for virtual peer to peer private networking, the project provides a VPN client using a custom protocol to be able to setup up a point to point dynamic virtual network. This differes 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. The project is open source and GPL (free as in speach) and runs on Linux and Windows XP, support for other operating systems is planned. Once established a VPPPN network behaves in a similar way to a normal IP network. To the end user this means you can setup an office network and drag and drop files between computers in a secure manner over the internet.
