Open Source vs. Academic Dishonesty?

Raul654 asks: "My university has a very vague Academic dishonesty policy. I have a small webpage with some code I have written (mostly C/C++ and Verilog), GPL of course. Someone warned me, rightfully so, that I might be in violation of the policy. Long story short, I have an appointment with Judicial Affairs in a few days (my doing), and I want to go in there with some persuasive arguments for why I shouldn't have to pull the page." The problem here is that the code on his webpage is code from previous programming projects. It basically boils down to the tradeoff of a student who feels pround about his work and a professor who doesn't want to interfere with the lesson plan he probably worked hard to produce. How do you feel about this?
