Currently, we do not discriminate against (of for) any particular kind of
agent -- within reason. In fact, we are trying to get our arms around the
question: what are agents and what do they entail. If we are going to
develop a modeling language, we need to understand that kinds of agents that
need to be modeled. So, if you have a kind of agent that you need a
modeling language to express and communicate about, this might be your
group. You task would be to determine what kind of graphical modeling
notation would best express and communicate "virtual actors." And, perhaps
you can find others in the Modeling TC that might share you quest.

Currently, there is a small subgroup of people working on "role." For us,
role is esentially a class (or AgentClass). When an agent is an instance of
a role, it acquires the properties of that role -- similar to an object
acquiring the structural and behavioral features of its class. For example,
when you say that particular Broker agent "performs its role", this implies
that the agent is executing the Broker-based behavior.
Does this make sense?
