    You can achieve PPP over SSH, which is ye old man VPN known for long :

    Although one may consider IP over TCP is a bad idea :

    Another solution is PPP over SSL. I use it with stunnel, and it works
    fine. Using a patched version, one can build tunnels though web proxies
    with authentication. See :

            http://www.stunnel.org/examples/pppvpn.html
            http://www.hsc.fr/ressources/outils/ssltunnel/index.html.en

    I like the bridged mode. Very convenient.

    It is included in testing and unstable.
