The same sort of things that happen when a program is changed or 
deleted.  If the service program has been deleted, you would get a 
runtime "can't find object" error.  If the logic has changed, your 
program will see the new logic (even without having been rebound).  This 
gets a bit more complicated if a service program is changed while a 
running job is using it.  I believe that the "old" version is used until 
the service program's activation group ends.  Can anyone give a bit more 
detail on this point?

From my point of view, there are very few times when binding by copy 
makes more sense than binding by reference.  Essentially, bind by copy 
is most appropriate for modules that will only be used in one (or very 
few) program objects.
