I use sshuttle all the time when working from "restricted" networks (car dealerships, airports, etc.) For some reason, my local Honda dealer has a guest WiFi that restricts outgoing traffic to a small number of ports, and apparently SSH isn't on that list, so I can't push/pull to GitHub. Firing up sshuttle on port 80 punches right through the filter and allows me to do real work while I wait for my oil change.
