There's a lot of good information already out there about the technical feasibility of current cryoprotective techniques, but much of it seems to gloss over technical details with a simple "we now know we can do x", without giving proof or citing specific examples. This FAQ fills the gap nicely.
BTW, my strongest chemistry qualification is that I've been sleeping with a chemist for the last decade and a half (I guess that'd make me a "lay person!" *snort!*), but I still found it quite readable. I'd like to turn this into a handout for the cryonics panels at Dragon*Con.
