Actually, I think the experiment did not have a particle traveling FTL, but instead it was a wavefront which was "traveling" FTL (e.g. the peak or trough of a wave) which does not violate the ligtspeed "speed limit", there being a number of similar types of occurences which can travel FTL, but all are equally incapable of delivering information.

I think this article discusses the experiment you were talking about:

I couldn't get to the article (not willing to register with NY Times from my work computer), but you could be right about the wavefront moving FTL, not a particle. It's been a while since I read the article...
