To some people using the "actor" attribute gives the sender some sort of routing or targetting mechanism. We know that routing is definitely not what it is there for, and targetting is only true so far as you can say "the node that will process this block will act in 'this' role". So, when we talk about a sender "thinking" that a particular node is the ultimate destination it sounds a little too close to targetting a node by something like an IP address rather than its role. A sender only has the notion of two things (w.r.t. targetting or routing), and that is "next" (since he's the one who opens up the socket) and "everything else" - which technically could wind up being "next" depending on the roles "next" chooses to take on. I get a little concerned when I see text that seems to imply the sender has any more control or knowledge beyond this. So, I don't believe the sender can ever really "think" a certain party(node) is the ultimate destination - he must always look at "next" as sort of a black box - "next" could be the end of the road or could be just the beginning - its a total unknown. -Dug
