Yes, everything works as you would expect. When you're holding an
object reference which you got with _this(), you can invoke on it just
like any other object reference. The call will be much more efficient
than a remote call.

With omniORBpy (and omniORB C++ too), orb.run() is never necessary.
There is no ORB main loop (that the user can get at), since everything
is handled by separate threads. If you look at the implementation of
orb.run() in omniORBpy, you'll see that it's just a while loop
containing calls to time.sleep(). orb.run() is just a convenient way
of preventing your main thread from exiting.

Cheers,

Duncan.
