HALO/billboard face rotate in object mode

is it possible to make an halo/billborard face to rotate in object mode…

i explain:
-create a cube, face select a face and put it in halo mode
-press p and the halo face works BUT it is in the middle of the cube :<

how can i make this face stay in it’s position iinstead of going to the object center?

i need this for to make a halo effect for a neon light, i need the halo face to turn 360° around the neon, not IN the neon

anyone?

you can’t do it outside of the game engine

and, halo faces need to be at the center of the object or they rotate weird, so if you want several you need several objects

…tooo bad
but maybe with a track actuator set on the object (with halo alpha) to the camera?
