+connection to any remote server to which you have secure shell (SSH) access.
+The only requirement is a suitable version of Python on the server;
+administrative privileges are required only on the client.  Unlike most VPNs,
+sshuttle forwards entire sessions, not packets, using kernel transparent
+proxying.  This makes it faster and more reliable than SSH's own tunneling and
+port forwarding features.  It can forward both TCP and UDP traffic, including
+DNS domain name queries.")
