Fortunately, it turned out that the goal can be achieved without doing this.

Good news: it _does_ work! :) Here is how to do it:

  1. start the X server on the client
  2. start the gnome session on the server
     (LTSP handles the first two steps automatically.)
  3. from your gnome session running on the server,
      open an SSH session to the client
  4. set the DISPLAY variable to the local X server (:6 in LTSP)
  5. start the bluetooth-applet
      (Steps 3-5 can be done automatically, from a script.)

If I do this, the BlueTooth applet automagically appears in the tray
applet! (This is cool, because the tray applet is sitting on the
gnome panel which is running on the server, but the locally running
bluetooth-applet finds it anyway.)

After this, the bluetooth-applet works just fine. (Asks for PIN, etc.)

I can handle remote audio devices with PulseAudio just fine.

Here you go :) 

This works, almost out-of-the-box.
