I just uploaded a new build of PulseParticles. This adds a new parameter to the MovieClipEmitter called "rootEffect". If set to true, the particles will be created on the root stage object, otherwise they get created on the parent clip like normal. I found this useful when tweening an emitter around the stage, but not having the particles move with the emitter. This causes the particles to leave a trail. Look for the star effect in this new demo since it shows exactly that off:
