I don’t know whether this guy knows what he’s talking about, but it sounds plausible:
Steven Sudit:
The speed of light in a typical vacuum false short of the speed in a perfect vacuum. Light is slowed by interaction with particles, even the virtual particles found in a vacuum. This is why it’s slightly faster when passing between plates exhibiting the Casimir effect, since that’s based on suppression of virtual particle creation. (http://en.wikipedia.org/wiki/Faster-than-light#Faster_light_.28Casimir_vacuum_and_quantum_tunnelling.29) So one plausible explanation is that, because of their minimal interaction, neutrinos travel at the speed of a true vacuum, slightly edging out photons.
There have been no indications that one can transmit information FTL using the Casimir effect, the work he mentions was on quantum tunneling time, which is a different beast.
