Controling music remotely with no wifi

[Bnightwing]

So here's the deal guys. I work at a community theatre with sound. I want to control the soundboard (the music aspect) while not being up at the board. See, there is a computer connected to the board that runs windows XP. It's not connected to the internet, so I can't connect to it using it's IP. When we usually use this computer to play the music. Usually if I want software I just put the .exe file on a flash drive and just install it as so. The reason I want to control it remotely is because it's hard to see the entire stage from where the board is set up. I was thinking Bluetooth, but I have no idea what I would use. Can I please get some input as to what I can do? If you guys have any questions let me know! If there is also a way to see what track is playing that'd also be great! Let me know your ideas that'll help!
