This is more or less the idea behind the Alcubierre drive [1]. If you have some source of exotic matter that has negative energy density it is possible to construct solutions to Einstein's field equations that permit faster-than-light travel by essentially bending the surrounding spacetime around the spaceship.

So lotsofmangos's idea is not quite the same, as it can be on-ship (although trying to use it as a FTL drive would either require infinite energy or rip the ship apart due to tidal forces (or, more likely, both).
