Just trying to wrap my brain around this stuff: The way I'd invent it if anybody cared to ask < s > is to have an referee-type object that would be responsible for the cross business object communication. Does that make any sense?

>This is an interesting comment, but I see a kink here. What if I have an app with multiple business objects that are mostly dis-similar, but all co-existing together. Sooner or later it's going to be in my best interest to let those business objects talk to each other. In that kind of situation I wouldn't want to depend on my upper level object (which I'm assuming would be my UI or front end tier) to pass the request from one business object to another would I?
