Good work Craig.  My comments follow.

1. I'd propose a name/parameter refactoring change like:

 - Names::Add (std::string, Ptr<Object>);
 + Names::NameObject(Ptr<Object>, std::string)

This would follow the verb+object function naming scheme.  I propose
that all the "Add" methods are thus renamed and reordered such that
the object being named comes first, followed by its name, followed by
the context if necessary.

2. I propose some syntactic sugar, hiding the above API from the user;
 essentially, a new Object base class API like
Object::AssignName(std::string); this makes things less verbose and
leads to changes like:

-  Names::Add ("/Names/client", n.Get (0));
-  Names::Add ("/Names/server", n.Get (1));
+  n.Get (0)->AssignName("/Names/client");
+  n.Get (1)->AssignName("/Names/server");
