Just a question...how would you like to connect? Since a remote is pretty useless if it has an usb cable attached to it Wi Fi is basically your only option, unless apple will allow us to use the bluetooth one day!
There was also some bunch of university students who developed a 'plugin' that plugs into the bottom of your phone and with infra red it can (after being programmed) be used on almost any device in your house.
Never really saw the need to have a remote for your household devices on the phone?? - Now you have to plug in an extra device onto the phone to use it... seems a bit dof. Just grab the blooming remote off the coffee table and switch the TV off/on.
