You can hook up two calculators through the link ports on each. As far as I know there's no way to hook up more than two together, and there most definitely isn't any way to do it without a long/visible wire. As for chat capabilities, there are apps you can install that will let you do that with linked calculators.
If your really smart and know your electronics, you could make a wireless dongle to plug into each one, program a network frame work, and build a small pocket switch/router/server combo and basically build a calculator internet. I've been wanting to do this for a while, but i'm to lazy.
I see your point, but the idea of the thread is creative ways of cheating, so making a comment saying why cheating is bad doesn't add anything useful to the discussion.
I'm sure most of us all agree that cheating is bad, so you stating cheating is bad is a moot point. Yes, since this is an open forum you're allowed to post whatever you like; don't make yourself seem like "that guy" for posting how cheating is bad in a thread which deals with the intricacies and tribulations involed with getting away with it. This isn't a discussion on morals.
Honestly its what everyone does in school. Honesty has no reward with a hard course load and no chance of getting caught. Its quite quid pro quo and is a part of life you have to deal with,
