If publish+configure is in there with configure optional (as has been  
suggested), then both methods work.  For something you want  
restricted to a specific configuration, you include the configure  
with the publish.  For something where you just trust the node is set  
up right, you don't.  Flexible protocol: the best of both worlds! :)
