Well, the technology exists to "decode" these addresses at the point of delivery. Assuming that the sorting facility bundled the mail in the order of the driver's route, you'd probably be able to make this work from the delivery point of view. I mean, UPS/Fedex/Amazon already have boxes and such sorted by route delivery with a device telling them what to deliver, etc. I'm more concerned that when an envelope shows up in my mailbox, that I don't know if it's addressed to me or my neighbor. I often end up with the wrong mail in my box, and I just do the nice thing of: a) not opening the mail; b) walking it over to my neighbor's box and placing it there. With this, I presumably won't necessarily know my neighbor's obfuscated mailbox and would end up having to open the mail in order to determine if I'm the intended recipient. Forwarded mail will also be hard or impossible with this scheme, as well.
