This is not a small task.  And it only works for the USA users.

Geolocate users based on their ZIP code, and use the US Census "TIGER" 
database to group them with the nearest city.

I don't know how to apply this on an international scale unless people 
are willing/able to provide meaningful GPS coordinates.

Having this capability buys you something else, though;  a user can say 
what ZIP code they're in and how far they are willing to drive for a 
keysigning.  This will lead to a lot of overlapping bubbles that people 
are willing to meet within.  At a "dumb" level you can merely send 
someone a list of who they can reasonably expect to meet based on 
mutually convenient travel range.  At a more intelligent level, key 
analysis could be performed to sort out who is close that has already 
signed your key vs. who has yet to sign it.
