This is a great companion to another paranoia-inducing post on HN recently (http://news.ycombinator.com/item?id=2267205 http://news.ycombinator.com/item?id=2267205) because it suggests a way to create your own plug-in-and-leave-it proxies to do whatever on the Internet without leaving any tracks. As you know, most hackers attempt to do this by tunneling through one or more compromised systems, but here is a way that might actually be somewhat legal: Go to any place where two public wireless networks overlap, and leave one of these devices in the overlap zone and connected to both networks. Arrange the networking so that you can tunnel out of one wireless network and back into the other. Do this in a few such places and you have a series of hops that can make it quite challenging to trace traffic back to you. Have your device retain no logs and include a remote power shutoff, so if somebody is chasing you from the destination network, by the time the physical plug is discovered (if it is at all, these things are easy to conceal) the router logs for the source network and ISP have long cycled. If you are doing something really nefarious, do all of this on a battery-operated Gumstix and leave it in a trashcan between a Starbucks and a public library. The battery would probably last you all day, and then the garbage truck will dispose of all evidence by next morning without any intervention.
