Freelan is a free, open-source, peer-to-peer VPN software that abstracts a LAN over the Internet. The program allows you to create any kind of network topology you like: from the classical clients-server schema, to the completely crazy hybrid peer-to-peer decentralized graph. It uses only standard, well-established cryptographic algorithms and makes sure that your communications are completely opaque to the outside world.
