Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Any experimental verification of superluminal communication?

Kind of.

And also here.

I can understand the group velocity argument, but what bothers me is that the rationale for 'proving' that superluminal communication can't happen seems very similar to the one that was being used to 'prove' with absolute relativistic certainty that the group velocity has to be less than c.

This doesn't 'prove' anything about what's possible, but it does make me suspicious of the rigour of the arguments that are being used.
