My answer is that they all do. The binding time does not affect that 
question because it doesn't change the computational power of the system. 
What changes is the style of the computation and how it is encoded.

That's because send(bagofbytes) and receive(bagofbytes) is all that is 
required, provided there is enough smarts already lying around to interpret 
the bagofbytes. In the 21st century we've replaced bagofbytes with 
(xml)doc, but that is just an encoding issue.

The various binding choices just shift the locus of where the smarts are 
located, and how much of it is embodied in code vs. declarations. 
Procedural semantics vs. declarative semantics is the what this debate used 
to be called when I was in graduate school. The buzz words have changed 
over the years, but the fundamentals have remained the same.
