This is an interesting question. At some level, do we separate the zoped
from an activity system based upon a stronger attribution of
intentionality to the zoped than to the distributed intentions of an
activity system? (The intentions of the agents within the
zoped/system, and even our research intentions in considering it a
context for learning.)
