As you can see in twisted.internet.protocol.Factory

    def buildProtocol(self, addr):
        """Create an instance of a subclass of Protocol.

        The returned instance will handle input on an incoming server
        connection, and an attribute \"factory\" pointing to the creating
        factory.

        Override this method to alter how Protocol instances get created.

        @param addr: an object implementing
L{twisted.internet.interfaces.IAddress}
        """
        p = self.protocol()
        p.factory = self
        return p

ReconnectingClientFactory inherits that method, so each TelnetClient
instance it builds will  have a self.factory you can use to access
your cmd list.

Hope that helps,
