The site offers no proof whatsoever, and just attempts to pass itself as credible by posting claims of performance. Or promises of providing proof.
Consider Artforz who made his own ASIC miner - he had no problems sharing quite a few technical details about his design. Nobody managed to replicate his results because of the huge initial investment required.
Epoxy on chips for preventing reverse engineering? There are sites on the net where you mail them your ASIC, and they will sand it down layer by layer taking pictures at high magnification.
Only thing to be hidden here is that the mythical ASIC doesn't exist. I would say that this is an elaborate scam attempt. Even if just a few people fall for it, it will still have paid off. Expect delays, stories of "Paypal problems", requests for additional money wires.
