See Greg Egan's excellent subluminal applet for an explanation:
http://www.netspace.net.au/~gregegan/APPLETS/20/20.html It only looks
like there is information transmitted. That has not stopped some
researchers from trying, even claiming actual information transmission.
But measuring extremely fast delays is hard and likely to be
experimental error prone; I believe it when they demonstrate a
repeatable macroscopic effect.
