If we had to find one way for the iPhone and Windows Vista to interact, it probably would have been via SideShow, Vista's secondary-display technology that gives you a small portable control board that you can tote around. The people at Ikanos Consulting have been fooling around with a SideShow webserver and are creating an iPhone-compatible version (along with DS, Wii, PSP, PS3) to control your PC wherever you have access. It's not available for download yet, but a beta should be coming soon. [Vistasquad - Thanks Matt!]
