This distribution was created by the Software Protection Initiative. The idea behind it is that government workers can use a CDROM or USB stick to boot into a tamper proof, pristine desktop when using insecure computers. The environment that it offers should be largely resistant to Internet-borne security threats such as viruses and spyware, particularly when launched from read-only media. LPS supports WiFi interfaces but doesn't current have support for printers or sound hardware. You just just need a basic web browser and a remote desktop client on a disc or to hand out to someone who might get lost with a more complex live CD.
