I have some friends who do live shows, and they use a click track - not so much to keep in sync with each other, but to keep in sync with the lights and projections (which are pre-programmed).
It's basically industry standard right now, for shows to be pre-programmed this way. It has some disadvantages, but IMO there are more pros than cons, mainly predictability. (source: I was making the guide tracks)
