        Well,  that was exactly what I was asking. You say it's purely
        a question of personal choice, I asked if there were any 
        practical or theoretical reasons for using one approach over
        the other.  Let's see if others have anything to contribute.

        Sorry, Benedikt, but when it comes to Create Phase Protocol objects
        I believe you haven't understood what's happening. For objects
        emplying this method, the object returned on the 'createEnd' call
        may be entirely different from the object returned by 'createBegin'.
        The Swarm documentation specifically reminds us to "reassign"
        the object (heatDisplay in my example) to make sure we end up with
        the final object and not the 'proto' object generated by createBegin.
        I stand by my story (and my questions),  as newspapers like to say.
