Lockers might work if they are close enough. E-Mail a one-time pass combination, digital barcode key, or bluetooth key.
I'd often rather just go pick up a package at the post office than being bothered with signature verification.
I doubt relying on neighbors to do common delivery would be practical. It might work for some close friends, but not in general.
