> The obvious solution is to have lockers at homes It's not uncommon to see this around dense housing. I've seen apartments where each unit has a small mail box, and there are (say) a dozen larger lockers off to the side. When USPS needs to deliver a package, they put it in one of the lockers, and then put the key to that locker in the recipient's mail box. I suppose the system assumes that none of your neighbors clone those keys, but it seems at least a step in the right direction.
