Yes, we need much more than that to send a 'message'.
It is not uncommon to interpret the Special Relativity
as forbidding *something* from going faster than light.
But there are, at least, five different possibilities:
1) No superlunimal matter transport;
2) No superluminal energy trasport;
3) No superluminal signals;
4) No superluminal causal influences;
5) No superluminal information exchange.
As far as I know the violation of Bell's
inequalities, for events at space-like
separation, does not demand the violation
of 1), 2), and 3). But for sure it demands
the violation of 4) and, perhaps, of 5).
Relativists [*] think that Relativity is the
theory of the space-time structure and not
the theory of the dynamics of particles and
fields, or the theory of anything going faster
or slower than anything else.

Relativity", Blackwell, Oxford, 1994 (and 2002).
