Nathan True’s excellent mobile hotspot – “Wouldn’t it be great if I could just plug my phone in… and have it automatically connect to the phone and serve its sweet, sweet Internet over a Wi-fi connection? Better still, have it transparently proxy all connections so that nearly all Internet programs will function properly? Maybe even prioritize certain types of traffic, or encrypt everything so my wireless carrier can’t spy on what Slashdot stories I like to read? All of those things would be just great. And all of those things are exactly those things which I set out to do (and/or enable you to do!) in this project. ” [via] Link.
