I remeber reading some years back in Scientific American (if I remember correctly) how they'd also managed to completely stop light and restart it using some exotic material. I think it was this same guy Robert Boyd who was involved.
The explanation given doesn't seem to violate relativity.

The article misses an important point. The pulse did not travel backwards so much as it traveled backwards in time.
