Could you push these changes back to the VRJuggler team to enable others to benefit from this fix as well. > However, now we have run into a different but related problem.

This is due to the particle emitter being transformed and the particle system itself being transformed as well, this causes a double transformation. To avoid this you need to move the particle system out from underneath your transforms an put it in world coordinates. Have a look at the osgparticleeffects example for discussion in the code about this.
