If we're talking about a relationship where one node gives work and another node does the work, this is the kind of relationship we see everywhere in manager/employee relationships without unnecessary and inaccurate baggage about ownership or autonomy. It's not even necessarily the case in a human master/slave relationship that the master gives work to the slaves, the key aspect is that the slave's work is done for the benefit of the master, but the actual assigning, coordinating and supervision of the work is not a core aspect of a masters role, and being itself work, would often be delegated to someone else.
