I'm only using one connection, that's why I'm using the proxy.  How would I know if I was getting duplicate submissions?  I don't recall seeing rejects/dupes/stales anywhere in the stats.  Presumably the proxy would tell me if something was rejected.  And presumably I'd notice if my payout wasn't in line with my hashrate.  Assuming that dupes/rejects are properly not included in my shares.

What about the S1 itself, or any other large mining equipment?  Has anyone reputable audited the output of the S1 to make sure all is copacetic?  200gh/s (OCd) is a lot of hashes to verify everything is working right.  Has anyone fed it controlled data and verified the output is sufficiently random to indicate it's working properly?  I think I know enough about mining works to think that a hash is a hash is a hash, so if it appears to be generating good hashes, presumably at sometime it would generate a hash that equates to a block?

Just thinking out loud here.
