I don't know, but he was/is involved with a stillborn cryoincs startup called Timeship. Also, he spoke at a cryonics and life extension conference recently with people like Ralph Merkle, and does seem to endorse present vitrification-based cryopreservation as "good enough." Search youtube for "fahy" and you should be able to find it.

Came across it pretty randomly, I found it quite intriguing. Cryonics is "routine" for human embryos, not far-fetched for humans at all. Makes the whole thing seem potentially very reasonable (and me someone who hasn't signed up and doesn't plan to).
