I'm trying to raise an exception on the Server Side of an SimpleXMLRPCServer; however, all attempts get a "Fault 1" exception on the client side.
RPC_Server.AbortTest()
  File "C:\Python25\lib\xmlrpclib.py", line 1147, in call
    return self.__send(self.__name, args)
  File "C:\Python25\lib\xmlrpclib.py", line 1437, in __request
    verbose=self.__verbose
  File "C:\Python25\lib\xmlrpclib.py", line 1201, in request
    return self._parse_response(h.getfile(), sock)
  File "C:\Python25\lib\xmlrpclib.py", line 1340, in _parse_response
    return u.close()
  File "C:\Python25\lib\xmlrpclib.py", line 787, in close
    raise Fault(**self._stack[0])
xmlrpclib.Fault: :Test Aborted by a RPC

Yes, this is what happens when you raise an exception on the server side. Are you expecting the SimpleXMLRPCServer to return the exception to the client?
You can only use objects that can be marshalled through XML. This includes

boolean : The True and False constants
integers : Pass in directly
floating-point numbers : Pass in directly
strings : Pass in directly
arrays : Any Python sequence type containing conformable elements. Arrays are returned as lists
structures : A Python dictionary. Keys must be strings, values may be any conformable type. Objects of user-defined classes can be passed in; only their __dict__ attribute is transmitted.
dates : in seconds since the epoch (pass in an instance of the DateTime class) or a  datetime.datetime instance.
binary data : pass in an instance of the Binary wrapper class
