Awesome, usbNetwork works! I can work on hotkeys again...
With wifi, it seems we can just connect to our devices over the network, even if they're not plugged into the computer. I'm trying this now, but want to make sure I get the security right. By the same token, be careful now when enabling "auto" mode of usbNetwork. You might not want everyone to be able to telnet to your Kindle, if you happen to connect it to your computer at a hotspot!
