can i change authetication code like this??

        if (!miner.Authenticated)
        {
            ((IClient)miner).Connection.Disconnect();
            return;
        }

or i think for bot miners that just making a overload. we must have some authentication timeout. if socket is not authenticate before timeout we just disconnect the miner.
