Vitrification also amounts to antifreeze poisoning. Quite a big deal if you're counting on full-body revival (which, granted, I don't consider feasible in the first place - cryonics is, in the best case, an information backup as far as I'm concerned).

That's the whole point: if we can if we can prevent water from expanding by freezing and keeping the sample under high pressure, thus making crystal formation harmless (probably), we can use less cryoprotectant. I don't know if it's possible to get rid of it completely, so I mentioned wood frogs, that already have all the mechanisms necessary to survive slightly below the freezing temperature. It's just their cryoprotectant isn't good enough to go any colder, but it's not so poisonous either. Also, they're small, so it's easier to find high pressure units ... (read more)
