Ah.

So there are a couple of points I left out of my original post:

  * darkstar runs the X display manager, and after login, the X window
    manager.
  * all three of the workstations (darkstar, nostromo, and sulaco) are
    headless (no keyboard, mouse, or display)

Follow-on questions:

  * Is the model for D-Bus like MS Windows?  That is, all of the
    applications (X clients) for my session run on one machine
    displaying in the same session on that same machine?
  * Are there plans to make this more like traditional X systems? That
    is multiple X clients on multiple machines possibly running as
    multiple users?

I'm not trashing on D-Bus, I'm just trying to understand how or if D-Bus 
fits into our environment.

Thanks, again.
