Found this one on LifeHacker.... a nifty portable app for your ipod (works fine on a USB key though) called DemocraKey.
Imagine carrying a portable security suite with you wherever you go. Walk up to any computer, quickly scan it for viruses, and then defeat any internet access blocks to view any website you want anonymously. It’s here, and the DemocraKey 2.0 Lite let’s you have it on your iPod.
That does sound a bit cool. Where can you get it from and how much? I have to say looking at porn at school would be a bit weird, I mean who else could be in the same room as you. Thats just weird.
