Hmmm... Well, I guess if you managed to modulate your data onto a gravity wave you could transfer it that way, but i guess that would need a system that could, at least partly shield gravity or increase gravity to create the carrier and modulate the data onto it, or perhaps you could play with a couple of black holes, but i don't se how you could impress your data at any usable speed(if at all) at something of that mass... Anyway, the data would still not move faster then light, as far as I know, gravity field propagation is limited to c...

I agree - I don't see how you could modulate the wave without expending a HUGE amount of energy that could be used to far more easily generate EM radiation. :-k (Mind you, if you could manage it, the energy expense would surely rid the airwaves of ShockJocks & Disco DJ's! May be worth it after all!
)
The wave would not be instantaneous - it would require time to propagate from source to receiver.
