Occasionally, I will VNC to my laptop when I'm not bringing it with me if I happen to find wi-fi using my iphone. I've always wondered though, if it is possible to control a host PC/Mac from an iphone using just the USB cable without Wi-Fi? Why would I want this? Just for the fun of using my cushioned laptop in my backpack with a cable wire running to my iphone while on the way to the bus stop. Any possibility of this?
