Dogie - However, shouldn't there be a distinction between manufacturers who mine on their own private pools (e.g. KNCminer or BFL with Eclipse MC) and those who distribute their hashrate among the public pools?  Mining in the public pools creates a (perhaps unintentional but still significant) positive externality to benefit all miners by lowering the variance of payouts and reducing their risk.  Can you refine the ethics rubric on your rating scale to reflect this distinction (something like a -1)?  Or do you not consider it to be a differentiating factor?  It would help get the rubric more granular...
