Thank you for posting these. One of things I want to emphasize is that these units plug into your router or a switch. They are essentially full fledged computers, their software just defines them as a miner. Each miner will have 2 things running, a BTC wallet, accessible from a web interface, and a Miner. The miner will be defaulted to mine on MiddleCoin, which mines the most profitable coins, and pays out in BTC. Middlecoin will send the bitcoins to the wallet on that system, and the web interface will allow the customer to transfer those bitcoins to their own wallet as they wish. There are more to these units than simple hardware.
Those are the default settings, but can easily be modified.
Again - I posted this on the LTC forum.. why are you talking in BTC if these are mining LTC (or scrypt/KH)?
Someone could buy 2-3 x ASICMINER 333MH/s USB miners that use 2.5/W each and mine the exact same BTC equiv for much cheaper and lower power consumption.. ??
or even better 1 x ANTMINER U1 @ 1.6GH/s (easily OC'd to 2GH/s+) for .06 BTC to easily mine more in BTC
