class Area (SQLObject):

class Office (Area):

class Home (Area):

SQLObject creates three tables, with a foreign key from Home -> Area and 
Office -> Area.

This means I can do:

class Person (SQLObject):
  areas = ReferenceJoin("Area"...)

and map a Person to a number of Areas, without having to map him to Office and 
Home via two join tables. 

Someone said superset mapping wouldn't be happening, which is a shame, as it's 
the most obvious and logical choice of the majority of OO mapping.
