Forgive the ignorance, are Block Erupter Tubes Antminer rigs? I think that message from ckolivas does not refer to the cgminer STILL being shipped by bitmain (potently loaded with the stratum redirection vulnerability, to mention but one security flaw).

We concluded some S4 testing in the last 24 hours and confirmed they work perfectly fine on this pool. While it may be a conflict of my own interests, I've helped the bitmain team so that they can modify the devices to work better on all pools.
