The Software Protection Initiative (SPI) under the direction of the Air Force Research Laboratory and the US Department Of Defense recently created Lightweight Portable Security (LPS). Like the name indicates, this is a small Linux desktop distribution that's designed for secure use.
LPS is designed to boot from a CD or USB pen-drive on any Intel-based computer. It doesn't install anything. It's designed solely to run solely in memory and to leave no traces behind when you're doing running it.
