Exam Question as a Paper Topic

Last year as a bit of a lark wrote up an exam question (yes, in a non exam course). Though it looks like the tech involved is not being incorporated into the next generation of gaming hardware, the issues are still live ones. As they may inspire a paper (or two) am posting the faux “exam question” here:

Both Sony & Microsoft have apparently developed used-game blocking mechanisms for their upcoming consoles. Please advise the on the legalities of their possible implementations, paying particular attention to Video Game Law cases involving interoperability as well as competition law/anti-trust questions. Consider also the law relating to hardware and software mods, as well as such freedom of expression/speech issues as you may be able to identify.
