I think a vices challenge would be cool too, somehow. Like who makes the best homemade flamethrower, or improvised weapons, etc. Or maybe some SE stuff, like a staff with make a fake ID or something based on those lines, post info on the internet(maybe giving them an email address, and you have to get as much info on that fake ID as you can with said email if you get what i mean. And whoever finds the most information, or finds the info the fastest wins. I'm more of a vices/drugs/SE guy rather than hacking, so I don't know if this would be up my alley if its only hacking and security stuff.
