Clarification on upstart-0.5 and dbus usage

[Garrett Cooper]

Hi again,
      There have been a flurry of emails passed internal dev lists,
and I believe (given past experience with dbus) there is some
confusion as to what the role is of dbus in the upstart project.
      So, I was wondering if someone could briefly discuss from a
high-level what dbus is going to do within upstart, or point me to [a
series of] link[s] with more information about the architectural
interfacing between upstart, dbus, and monitored processes.
Thanks,
-Garrett
