If you invoke the CFC as a web service (using ?wsdl on the URL), you get the result back as a SOAP response (XML). If you invoke a CFC method via a URL without specifying ?wsdl, you get the returned value as WDDX. If you invoke it from Flash, the response is in AMF.
Also, in CF8 you can specify returnFormat on the URL with values for JSON, WDDX, and plain.
