What would you use these "addresses" for? Do you write this on a letter 
you're mailing? Or is it just something that you might expect as output 
from a person or router, and thus any landmarks can be used?

I ask because this sort of description is used everywhere. One might say 
"at the end of the road, past Sand Lake Elementary School" rather than 
"8249 Buena Vista Woods Boulevard", but that doesn't make the former any 
kind of real address. It's simply a spatial description that can be seen 
by looking at the map.
