University of Toronto has been doing it for years (Score 1)

We're way ahead of you, Georgia Tech; the University of Toronto's Computer Science department (www.cs.toronto.edu) has been using software to detect plagarism in code for quite a while now.

Firstly, it doesn't just look for exact matches of code. That would be stupid. As far as I know, it uses certain algorithms that look for similarities in, for example, the structure of various classes used on a program. Presumably, they would also look for blatant similaraties in execution patterns.

As for CmdrTaco's ignorant comment on his deluded preception of the "real world" - obviously he doesn't understand the purpose of a university education. As a student, I'm glad that universities take such measures to prevent people from copying code. Especially when assignments don't involve implementing code for the sake of learning a language, but rather involve creating algorithms from scratch, for the purpose of understanding more fundamental concepts in computer science.
