I think we agree on the concept, but the terminology previously  
confused me.

When you said, "alias," I read that as meaning, "different names for  
the same service."

Now I see that when you say, "alias," you mean, "different services  
on the same port." (I'd call that a "collision", except in the  
special case of a new service which is a compatible extension to an  
old one on the same port.)
