Cryonics does not freeze tissue. The current method involves vitrification, not freezing. Vitrification is an ice-free process in which more than 60% of the water inside cells is replaced with protective chemicals. This completely prevents freezing during deep cooling. Instead of freezing, molecules just move slower and slower until all chemistry stops at the glass transition temperature (approximately -124C). Unlike freezing, there is no ice formation or ice damage in vitrified tissue. Blood vessels have been reversibly vitrified, and whole kidneys have been recovered and successfully transplanted after cooling to -45C while protected with vitrification chemicals.

1) Huge compendium of human knowledge.
2) Runs off of commonly available, easily stockpiled batteries
3) Runs for a whole year off of one set of batteries (swap Lithium for alkaline, it should run for a decade)
4) Sunlight-readable
5) Compact, sturdy and durable

Hell, at those kind of power usage levels, you could hack a small solar cell into it and it should work anywhere you've got sunlight. Imagine a complete breakdown of civilization as we know it. Books are heavy and inconvenient and make good kindling. Without electricity, compact digital forms of information retrieval become impossible. What do we use to rebuild civilization after a couple generations of this send us back to the dark ages? This thing! It's PERFECT.

http://paranoidlinux.org/ is a project to create a distribution which assumes the user is under assault from the government. Right now, it's a vaguely locked down version of Ubuntu, but someday this might be pretty cool.

In the meantime, just run NetBSD and full-disk encryption.

From wikipedia:
NetBSD provides various features in the security area. The Kernel Authorization framework (or Kauth) is a subsystem managing all authorization requests inside the kernel, and used as system-wide security policy. It allows external modules to plug-in the authorization process. NetBSD also incorporates exploit mitigation features, ASLR, MPROTECT and Segvguard from PaX project, and GCC Stack Smashing Protection (SSP, or also known as ProPolice) compiler extensions. The Verified Executables (or Veriexec) is an in-kernel file integrity subsystem in NetBSD. It allows the user to set the digital fingerprints (hashes) of files in the system to monitor by the Veriexec, and prevent the execution of them. For example, one can allow Perl to run only scripts that match the fingerprints. The cryptographic device driver (CGD) provides functionality which allows using the disks or partitions (including CDs and DVDs) for encrypted storage in NetBSD.
