OK, here is what I have done:

/etc/rc.local gets this line added:
su - len -c /home/len/.bin/startfake.sh

startfake.sh looks like this:
------------------------
#! /bin/bash
# Len's try at creating a dbus session on a no X system
# September 18 2012

rm /home/len/.bin/setsession

# Pretend we are X
echo "DISPLAY=:0" >/home/len/.bin/setsession

dbus-launch | grep ADDRESS >>/home/len/.bin/setsession
dbus-launch | grep PID >>/home/len/.bin/setsession

-------------------------------

~/.profile gets this bit added:
-------------------------------
    if [ -f "$HOME/.bin/setsession" ]; then
        . "$HOME/.bin/setsession"
    fi

export DISPLAY
export DBUS_SESSION_BUS_ADDRESS
export DBUS_SESSION_BUS_PID
-------------------------------

here's whats running after boot:

Hmm, jackdbus isn't running till I ran jack_control start on the other
login. jackd can also be run ok instead of jackdbus.
