This is one possible way in which the system may be set up. But if you
have a system set up in a controlled environment (a single machine) you
would typically have *one* IH (one instance of libIntegra). Each bridge
would tap into this single instance (if I'm not mistaken libIntegra
currently is a singleton and may not be loaded in multiple instances on
the *same* machine - this should be fixed though). With the current GUI,
built in Max, the GUI has its own OSC host that registers with the
libIntegra instance. IOW even though its running on another machine it
doesn't need the library.

If the system has multiple IHs only *one* may read and save module and
collection defintions (libIntegra may be compiled with the IH
functionality *only*). And in this case they communicate via OSC through
libIntegra.
