  I do not pretend to know all the potential forms of a Web service. I 
certainly hope to be surprised!
  In addition to this loose association, there is a vast range of other 
kinds of Web service. My nose is acute for some kinds of short-cut 
`solutions' that I know will not meet the needs of people wanting to 
develop and use Web services.
