This is done with the 'SmNexternalNotifier' attribute in the SmArg list sent to SmOpen(). I was planning on just throwing this into the event loop. I'm not sure if we can currently do this from the module API or not. The route I would take with a subprocess is to use (make-event ...) with data from the subprocess. -Bill P.
