There's some misunderstanding here.  What's missing here is a way to
start emacs and not create any frame, just have it run as a daemon (and
do not quit when the user logs out for example).  Then create frames
connected with that running emacs process.  The method of connecting to
the running emacs:  dbus or emacsclient is not important.
