First - thank you for rooting your response in a working draft. Citations 
would be helpful.

Second, I am concerned about the word "agent" as we used it. I belive the
agent Mike C refers to was "a wrapping around a 'turtle' that could
implement an interface...or something similar.

That's not my reading of the working draft. My understanding is that the WSD
proposal is for a "service" to have an attribute that points to a URI. This
URI identifies something other than the "service" itself. Also I thought
that everybody pretty much agrees that an agent is different than a WSD
service.

My understanding of an agent is that it is a piece of code. Again, if I
replace that piece of code with another because of any reason, do I get a
different URI? And why should the service care (assuming the semantics
remain the same)?
