For anyone with (non-root) SSH access to remote servers, sshuttle provides a very simple alternative to the key-juggling headache of configuring VPN. All you need is root locally (as it needs to modify iptables) and python installed on the opposite end. On the Virtual Machine I am using for some Twitter-related software development, I just turned off OpenVPN and replaced it with the following:
sshuttle --dns -vvr firstname.lastname@example.org 0/0 -x 192.168.8.0/24
and behavior seems to be the same, ie. everything (including DNS) is sent through the SSH tunnel, except traffic going to the local 192.168.8.0/24 subnet. But, it seems there is no automatic restart if the connection is broken, sshuttle just errors out. Enter restartd, with this line in /etc/restartd.conf
shuttleTunnel "sshuttle" "sshuttle --dns -r email@example.com 0/0 -x 192.168.8.0/24" " "
(Obviously I am using an SSH key here for passwordless server login....)
It is worth reading  to understand that this tool is meant to restore packet loss and thus TCP's automatic speed throttling to an SSH tunnel connection, thus improving overall performance.
