Don't have the address or email, but doing this is just a
simple loop in a shell script.  Here is an example in the
Z-Shell which makes a proxy server running behind a firewall
available on a remote machine.  This is run from the system
running the proxy server but could be run on the other
system by changing "-R" to "-L".

    while true
    do
    echo ">>> Connecting <<<"
    ssh -R 3128:localhost:3128 -c blowfish -g  \
        user at host.com ping -i 5 localhost
    sleep 2
    end
