Interesting. I'm extremely skeptical that an individual preserved that way could ever be revived. One has all the ice crystal formation problems that modern cryonics have solved and also is keeping the person at a much higher temperature so one will have a lot more chemical activity.
Maybe some of the organizations that practice actual cryonics should send representatives to try to recruit people?
Despite the creepy symbolism I find it rather unlikely that a real superintelligence would raise the dead. If it did, though, the difference between cryonic preservation and cremation seems negligible to me. (This might sound absurd for many obvious reasons but that I'm willing to say it anyway should be evidence. After all, I probably would have thought it absurd too, and yet I now think it's totally non-absurd. Therefore there's probably a non-obvious consideration, or a set of disjunctive and non-obvious considerations, that counters the initial absurdi...

I'd imagine the efficacy is halfway between proper cryonics and embalming and burying; the more interesting part may be the festival. Nederland is a small town 20 miles from Boulder, CO. I doubt the festival attendees are cryonics advocates, but they don't seem prone to the negative associations corpsicles often raise. Perhaps it's just because Boulder, Colorado is full of weirdos, but I wonder if there are more exploitable effects in play.
