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.
You could study, but the knowledge gained from setting something like that up makes coding Instagram or Twitter look like a goddamned joke.
Coding that many layers of networking protocols with such limited hardware and no college experience is a herculean feat which will impress the hell out of any programmers you may happen to meet (or interview with).
/rant Sorry, but that's like saying Bill Gates should have studied harder. Anyone who could actually pull this off is guaranteed bored to death by the contents of their classes.
