There's really two completely different principles at stake:
a) Information can't travel faster than light, or causality is violated
b) Material objects can't be accelerated to the speed of light
How fast different phases of a wave travel is not such a big deal, if you
can't get information out of it. I'm sure everyone remembers E-P-R and
quantum entanglement of photons, right? Even if transluminal data was
available, if you can't interpret it without out-of-band information its not
really a message.
