Seriously though it does come down to your brief. This reminds me of a spot quiz that my girlfriend's students were set on their IT for humanities course. The entire group were set the task of finding answers to a whole lot of general questions (How many computers in the computer lab, whats the classmark of a particular library book, how mutch does the local print shop charge for photocopies etc.) and given an hour to find them using whatever resources they wished. They could even have asked the supervisors the answers if they liked and that would have been ok, that was the brief.
However I aggree with tachyon, this student was definatly outside his brief. He was expected to present his own work as is usual for a programming assignment. He chose to ...ahem... present someone else's. Not smart, and also not the way to learn.
Remember that amateurs built Noah's Ark. Professionals built the Titanic.
