You may have heard of the Tor network which if affectionately known as the onion router. Tor is a anonymity software which is free and open source. The trouble with Tor is that it can be dreadfully slow for every day use. Moxie Marlinspike has come up with a solution called Tor tunnel. Tor tunnel basically uses just the Tor exit node rather than all the hops in between. Of course this is not as good a solution for anonymity however in situations where you only need to be mildly anonymous it can be effective.
