I wonder if anyone here has experience with any of the privacy-based live distros. I was able to find this list:
http://www.kimpl.com/anonymous-distros/. The TAILS and Liberte projects look the most promising. I think the ideal distro would have the latest Tor bundle and bitcoin client, in addition to TrueCrypt, GPG, etc. This would be nice as you could boot up from just about anywhere, load your encrypted bitcoin wallet from a flash drive, connect via Tor or I2P, and conduct your business securely (assuming the hardware itself wasn't compromised). I know there was LinuxCoin, but that project seems to have been abandoned.
