OpenSSH version 4.3 introduced a new feature: the ability to create on-the-fly "Virtual Private Networks" via the tunnel driver (the so-called "tun" driver). This allows you to create a network interface that bridges two physically disparate network segments in different locations.

"The Debian Installer lenny release candidate 1 was released on November 12th, which inspired me to check it out and give the installation over ssh a try..."
