Like in "SugarCRM", would be helpful one field in contact called "Report to", with a link to his "contacts boss".
So, in the page of the contact, you will see the name of the boss of this contact and a link to his page.
Example: htp://i51.tinypic.com/14o3wp2.jpg
To set the "boss of this contact", you simply select the contact from a list. My company needs it.
Thank you
