Hope this is the place for Driver questions:

In the SOAP driver, if a request comes in on the Publisher Channel, is
there a way to put the result of the command (e.g., success/error) in the
http result that the SOAP client recieves from their request? By default,
the client gets back 404 if there is a connection error, or "200 OK" on
successfull connection (but there is still a "200 OK" if the driver has an
error in processing the request).
