It's entirely up to you.  I personally favor 'dm.remove(ob)', as to me it's 
like removing an item from a list or set.  peak.schema will use this 
approach when it arrives, as it will treat a database as just a giant set 
of objects.  So 'db.add(ob)' and 'db.remove(ob)' will be used to add and 
remove objects.
