There's something similar to this (but better in my opinion) built around OpenBSD. It routes all external TCP traffic through Tor, and even spoofs aNY subtle OS "fingerprints" to look like something else to the outside world. http://sourceforge.net/projects/anonym-os/ -- Hand Crafted on Mon.

Flash is writable, so can be tampered. The critical secret (the server's key) is in the ro part. So what good is it? Really, guys. If it is protection against governments you want, you are barking up the wrong tree. Too difficult. -- Lionel

What do you think about to start TOR with Knoppix Linux booted from a CD/Rom?

These papers are by Peter Gutman himself. "7. Methods of Recovery for Data stored in Random-Access Memory" "8. Erasure of Data stored in Random-Access Memory" http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html Data Remanence in Semiconductor Devices -- all 19 pages http://www.cypherpunks.to/~peter/usenix01.pdf It's been a few years since I've read these articles personally.
