The "Where it is" might be convenient to have in a comment field. I don't 
think I would relate the post box address to the building unless it's 
attached to, or in the building, but if you have a valid reason for doing 
so, go for it.

In Mike's situation, where the post box address is similar to but not 
identical to the addr:housenumber, then I think it's valid to include it. 
And, even if it is identical to a building address, ref= is probably a 
better method than addr:housenumber=.

You wouldn't be able to route to a specific post box (or mailbox as we 
call them in the States) with a general purpose navigator program, but I 
think the need to route to a specific post box across town, would be a 
pretty unique need that could be met with a special purpose router that 
searched for ref=* instead of addr:housenumber=*.

Anyone for OpenPostBoxNavigator?
