With the attached patch you can use a custom function to update the particles of an emitter node. Just define a normal C function, and pass it to h3dSetUpdateFunction for that node. Attach the particle system to your physics layer, use it for displaying billboards... Have fun!

It even works together with Python ctypes, albeit slow.
