I don't understand how this will work - first of all, how do you just show up at a random address to receive equipment, and second of all, how does this at all stop the NSA from just putting its spy devices in everything that Cisco ships out? Seems to me that in the former case, you run the risk of getting ripped off, and in the latter .. well, the NSA will just find other ways, besides interfering with the UPS man, to get its tendrils in your soup, so to speak ..
Unless it's just a PR trick to soothe concerned customers.
