1 Comp w/ DVI out: reverse KVM switch, 2 cables?

Hey guys and girls, i have a question about my setup...

I have a computer and home theater nearby, and am looking into a sweet wireless keyboard to browse the internet on my 41 inch samsung, from my couch. I already bought the DVI to HDMI. I was looking on Newegg.com for a cable with one female DVI, and 2 male DVI on a switch, but could only find the contrary: 2 females and one male.

It seems everyone with two computers and one monitor doesnt want to have to crawl under the desk, or reach behind the monitor, but those with two displays and one computer enjoy the time on their knees. Do you guys know of anything that could help me solve the problem of getting out the flashlight every time i want to kick back on my couch to browse?

Btw i have SLI cards, and that means two DVI outs, but up to now i havent been able to figure out a way to efficiently switch from one display to another. Price isnt a problem here i just want that nifty button to put under my desk, so i can snip snap this whole process without needing knee pads.

thanks in advance, Ian
