Couple of random thoughts about cryonics:
It would actually be better to have cryonics legally recognized as a burial ritual than as a cadaver experimentation. In that way it can be performed on someone who hasn't formally signed a will, granting their body as an anatomical gift to the cryonic service provider. Sure, ideally it should be considered a medical procedure on a living person in a critical condition, but passing such legislation is next to impossible in the foreseeable future, whereas the former sounds quite feasible.
The stabilization procedure should be recognized as an acceptable form of active euthanasia. This is probably the shortest way to get to work with not yet brain-dead humans, and it would allow people to trade couple of months or years of rather painful live for better chances at living again.
Insulin injections should probably be a part of the stabilization protocol (especially in the previous case). According to "Glucose affects the severity of hypoxic-ischemic brain injury in newborn pigs" by LeBlanc MH et al, hypoglycemic brains sustain hypoxia much better than normally. That totally makes sense: oxygen is mainly consumed for glycolysis, so if there's nothing to oxidize, oxygen consumption will decrease.
Some of the major problems of cryonics can probably be solved by preventing water from expanding upon freezing. According to 1 and 2, ice is denser than water at about 30 kbar. That is a bit technically complicated, but I would speculate that with this trick we could have reversible freezing in wood frogs right now.

That would destroy cryonics companies who make money via insurance that depends on people legally dying.

What do you mean exactly? If I understood it right then vitrification is done to prevent ice crystals from forming. Do you mean something different?
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
