   Except that (as in varying-speed-of-light cosmological models) it might   
   vary with respect to ALL possible standards, in which case it wouldn't   
   make sense to define any sort of length with respect to that speed, just   
   as one doesn't define any length with respect to the speed of someone   
   riding a bike, say.
