title: Is it possible to return a reference property in an App Engine computed property?
body: <p>I have a model with an attribute that is a reference to another model. The model it references depends on some logic. Is there a way to have a computed property that gives me the same ReferenceProperty niceties (reverse references, dereferencing)?</p>
  
  <p>So far I the computed property stores a db.Key, but this is not optimal. Can I have a Computed 
  Reference Property?</p>
