From a customer's or system integrator's perspective:  I want to access 
the service that tells me where my package is.

From the network architect's perspective:  I've chosen to use REST.  The 
way REST models this is to provide a "resource" that has as its state the 
location of the package, mint a URI a for that resource, and use HTTP GET 
to get a representation that tells me where the package is. 

I think you are going just a bit to far in identifying SOA with plumbing. 
SOA is, I think, closer to what I've set out as the customer's and system 
implementor's perspective above.
