Definitely possible. I have mine setup that way now. However...100 meters is a long ways away. Mine is currently about 35 feet away. You can get HDMI/DVI cables up to 100-150 feet or so (might need an active repeater/extension). I have my USB using 2 15 foot active repeater cables. However...you can only daisy chain so many usb active repeaters, so if you have to go a real long distance then you'd be better off getting a USB extender via cat5. You can get usb 1.1 extended a long ways with cat5 for 40 bucks or less. If you need usb 2.0...I think you still can, but it gets quite a bit more spendy for the extender.
Let me know if you have any other specific questions. Short answer...yes you can do it. You can easily and fairly cheaply do distances of 50 feet or less. If you need longer distances 100+ feet...you can still do it, but it starts to get spendy.
