FR works because for the most part every face has identifiable landmarks (eyes, nose, jaw line, etc.) that can be scanned for. Doors have similar features, but with less regularity. Entrances to homes and buildings vary widely in their materials, hardware location and type, etc. It would be much more complicated than you might think to accurately devise software that would accurately identify a door (and beyond that, the correct door on a building) to deliver to. And FR is coming along, but is still very unreliable in "live" situations (unlike photo recognition of FB and Picasa).
