There is no standard way to do it, so you won't find it in the CORBA
spec. omniORB does it with a special POA. You use code like this (in
Python since it's easier to read)

  orb = CORBA.ORB_init(sys.argv)
  ins_poa = orb.resolve_initial_references("omniINSPOA")

  servant = MyImplementation()
  ins_poa.activate_object_with_id("example", servant)

  ins_poa._get_the_POAManager().activate()
  orb.run()

The object is now available as corbaloc::host.name:port/example. You
should pin down the port number with -ORBpoa_iiop_port in omniORB 3 or
-ORBendPoint in omniORB 4.

Cheers,

Duncan.
