That sort of relationship model is (IMO) a necessity for Drupal's 
long-term health. Like everyone else I took a crack at implementing such 
a model and have had it sitting in my sandbox for a few months.

If we do use 'relationships' as the basis for translation, I hope we 
take the time to do it in such a way that taxonomy terms, buddy lists, 
and other kinds of connections can be represented as well.
