I dont know what OS your running but if u get Windows2000 pro it comes with whats known as Terminal Server

when you have Terminal Server active you can go to a browser and type in the terminal server address you set it and then u actualy see that computer in the browser and if u want u can full screen it so where your actualy USING that computer just using your screen...... i love that feature personaly

I used to terminal server to a REALLY powerfull server my friend had, it was great cus i use that wonderfull machine and it didnt have to sit at my house

I hope this helps
