So.. thinking a bit more about this, how about this

 1. Make each instance of a session bus register with the system bus
    and specifically pass the address $DBUS_SESSION_BUS_ADDRESS. Could
    have a fancy API to allow (privileged) users to list sessions and
    even connect to a service on the session bus. Could be useful for
    out-of-band information, e.g. requesting to put up dialogs and/or
    notifications from system-level

 2. Extend the dbus protocol to include $DBUS_SESSION_BUS_ADDRESS for
    every method call

In a way this nicely ties the system and session buses together.If we
want this we obviously need to do it before 1.0. The patch should be
simple and I even volunteer to do it :-)

Thoughts?
