The dbus support relies on about 4 hooks provided by the HID interface
which are only implemented in the GTK and Lesstif HIDs.

They relate to timers and file-watches (for IO). These allow the DBus
library to integrate with the main-loop of the running GUI. It won't
work without them, so I guess the easy answer is.. no, the Batch HID
does not support DBus.

If anyone had a use-case for a DBus enabled batch HID, then either the
hooks could be implemented (along with a home-brew main-loop), or more
sensibly, make the batch HID dependent on GLib and its main-loop, then
take the hook code straight from the GTK HID.
