Is "interface" the widely accepted term here? I can't help but 
think you're talking about network interfaces; hence I don't get 
the notion we are converting from one protocol to another.

Re. "gateways that are SOAP nodes are not SOAP intermediaries", I 
am reading Henrik's answer[1] somewhat differently.

He says: "gateways are not SOAP intermediaries", meaning SOAP 
intermediaries do processing at a higher level: they understand 
and possibly process the message; gateways typically do not.

But he then adds: "One could imagine SOAP intermediaries being 
underlying protocol gateways", meaning a SOAP intermediary might 
not process the message at all but simply switch protocols.

I think this fits perfectly with the figure at [2] and my earlier 
note [3].
