The usual approach is to save the data (`cmd' in this case) on the factory and use `self.factory.stuff' from the protocol.  The `factory' attribute is set on the protocol class by the default `buildProtocol' implementation.  It is not available in the protocol's `__init__', but is available by the time `connectionMade' is called.
