	Right; the problem is: getting notifications of newly registered
components with b-a-s is not possible, something we could/should add to
b-a-s I guess.

	Well; you can use the ORBit_small_[un]listen_for_broken API, it's a
slighty clumsy thing though.

	An alternative may be to have your application contact the applet to
set properties on that instead - that is assuming you control both ends
of the pipe :-)

	HTH,
