The Service and Requester are individual roles because we consider them to 
be significant to the architecture that we're defining.  You may consider 
"Advertizer" to be a significant role also.  That's a valid point of view, 
and is illustrated on Slide1 and Slide2 (with different labels).  But the 
point of Slide3 and Slide4 is to show that it isn't the ONLY valid point of 
view.  The "Advertise" arc in Slide4 does not require a third party role 
any more than the "Interact" arc does.  Physically there might be all kinds 
of intermediaries between them, but at the level of architectural 
abstraction, they are both direct connections.
