In the pacelines I've ridden the standard warning to the rider on your wheel is to say "braking" or "slowing" when you have to slow down for traffic or other obstruction.
With the current availability of bright but low power demand LCD lights I'm surprised someone hasn't come up with brake lights and turn signals for bikes. The dedicated roadies wouldn't bother but commuters, etc. might benefit.
