Actually, this is orthogonal. 'Pass-by-construction' (pbc) objects  
are transferred over the network by serialization, and are not  
necessarily Selfless. (The primary use case is that an unum presence  
is pbc.)

The combination of pbc and Selfless results in the  
indistinguishability you mention.
