This is tripping over some conflation of identifiers.  There can be
many identifiers in play at one time, for the same or different
functions.  An ID that you would use to find a process to talk to does
not have to be the same as the ID you would use for session control or
session authentication.  A HIP HI can be used for both (but doesn't
have to be), but afaik a Bundle ID cannot.
