I thought it strange too. Wifi on the DS is in its infancy, I couldn't conceive of how the university would have even heard of it yet let alone setting exams on it. And why that specific hardware? What if you didn't own one? If it's something you want to do, and need help, why don't you say so. I don't think the technology has come far enough for anyone to give an answer. And, does it mean the DS has to transmit a control signal? I admit I know nothing about this, but is the DS capable of transmitting? What range (distance) are you after? It would be more viable to simply buy a webcam (or whatever) that comes with a remote control. Anyway, enough from me, I'll leave the floor to those who actually DO know something...
