Using the new IR ANYWHERE IR OVER IP MODULE you can send web requests that get turned into standard consumer InfaRed signals, to control your tv, hifi units. I have thought for along time that manufacturers should just be adding web control to all new electronics, but this seems like it could be a good interim measure.

This then allows app/web based control of you home entertainment system, which would be very slick from an iPhone/iTouch/iPad.
