You need to run on both.  The process address space is still on the
XDMCP server, so the system daemon must be running there.  The clients
have mice and keyboards so they need dbus and hald.  You will also need
to start your dbus-enabled processes with dbus-launch, or start your
local X session with dbus-launch so that a session bus is running.  This
session bus will also be running on the XDMCP server.
