In our interpretation of GR, both forces and information can be transmitted much faster than light. In the customary interpretation, neither is possible. The new technical paper, “Experimental Repeal of the Speed Limit for Gravitational, Electrodynamic, and Quantum Field Interactions”, by T. Van Flandern and J.P. Vigier, in Foundations of Physics v. 32(#7), pp. 1031-1068 (2002), deals with precisely this issue, and argues for the new interpretation.

Similar papers dealing with the "speed of gravity" issue appear on this web site. -|Tom|-

Basically, there's always an aberration between light and gravity of moving source. One can encode the info by this aberration, transfer will be ftl. Hence, there's nothing in the GR itself that really forbids ftl info. I.e. the spacetime is bent near-instantly, up to the precision of small radiative term. But the mechanism described requires an "intelligent receiver" and pre-established one-way communication transmitter-receiver.
