What would you present?

In a couple of weeks I'll be presenting to a class of paralegals-in-training, talking about the legal aspects of compliance in marketing online (CAN-SPAM, DMCA, CDA, etc.). I'm pulling together information about various cases that might be most interesting to share with the class and generate topics of discussion. Could I impose upon you, dear reader, to share with me what your thoughts are here? Got any links or info you'd like to share with me? What cases do you think merit looking at? Gordon v Virtumundo, for starters. What else? Thanks in advance for your thoughts!
