But nothing is going faster than light in your hypothetical.

The signal is.

You are implicitly assigning a reference frame to the communication itself

So make it infinitely fast. The argument still works. In fact, it's simpler.

No, it isn't. Information is being communicated but nothing is 'going' anywhere. If it were quantifiable, then it would not be "spooky" action, now would it? =)

I don't see how unless you introduce a third reference frame interacting with the first two (which in principle is always the case anyhow, which is why I said that the causality problem is ultimately unresolved).
