I read this nice article about Android SSH tunneling in order to bypass firewalls. It reminded me what an old friend from HELLUG used to do from his laptop. He had a shell account in university's box and, if I remember correctly, from this box he created another SSH tunnel to a similar remote box. Nice and easy trick. You can use red-pill or buylr to see some lists that include free shell services.
