why don't you just use a simple tool like messenger to view him that is the easiest set up. go buy a webcam set it up to a machine w/ a connection and your done.

pcany, netop, or gotomypc are all option of taking control of a machine at home; obviously then all you need a cam hooked up in the room/rooms of choice.

if you want to get really creative why not just get a few nanny cams setup up your own webserver and type in domain for instant nanny cam
