A four head KVM extender up to 820 feet from your workstation, Matrox's new Extio F1400. Basically it's a remote graphics unit that shifts your desktop experience from right next to your box to wherever you want it within 820 feet, via high speed fiber optics back to the GPU. For a desktop extension without a thin-client solution, the Extio F1400 is probably as sophisticated (and expensive) a solution as you're gonna find.
