There are some KVMs on the market which sends the signal over a standard ethernet connection.
You can place the KVM in the room where your rig is and then you need only a network connection to it. could be wireless of cause.
I think solutions like TeamView, RDP, VNC or similar products would not fit you because you loose to much speed. As far as I understood you like to work on the rig like sitting in front of it. So the wireless KVM is a choice or the other wirless alternatives already given in the thread.

You can game remotely via RDP on Server 2008+ terminal servers...there is no lag, especially if you are on the same subnet/network. So saying RDP or VNC wouldn't work is silly...TV would have some slight overhead
I read through the OP as well as his responses, and I am not seeing any place where he said he was concerned with lag. He just said he wants to be able to control it. Maybe I missed it....
If he isnt worried about lag then a free solution like TV would be better than dropping money on a wireless KVM.
Yeah, I was just refuting the other person's claims that VNC/RDP would not work. If he is concerned about lag, I was saying he could go that route. I even have some old HP thin clients with Windows XP Embedded if all you need is a jump point (something to RDP from to the Win8 rig). PM me if you are interested, as I have a slew of old thin clients.
