You're right that the delivery guys aren't too concerned so long as it's non-commercial. So a roommate or neighbor or the apartment front office or whatever is no problem. That's how you can get USPS packages at your work even if it's a huge building; the mail department at your work isn't a separate business that charges you for the accepting your mail. Once it's clear that it's a mail accepting for hire kind of business though the USPS guys will be sticklers about it. Ultimately I expect that these businesses will get bought up by UPS or FedEx for the software, the already designed physical boxes and the small but existent network of facilities. Once that happens they will become a nationwide thing but only in areas where the drivers have to do lots of re-delivery. They will look at it as a cost reduction more than anything else. At least that's my take.
