    Hi Lars,

    OpenGFS uses sockets, see:

    http://cvs.sourceforge.net/viewcvs.py/opengfs/opengfs/src/locking/modules/memexp/moduleops.c?view=markup

    Yes, it's all to be opened up. If you don't mind, I'd prefer to hold off
    discussing the infrastructure details until the code lands.

    Regards,

    Daniel
