I've thought of a pretty fool proof method to communication securely and efficiently. Both parties (Limit 5) can download LogMeIn-Hamachi VPN client then install it, then again both parties must then download Vadalia the Tor VPN and once it's up a functional you apply the Sock5 settings from Vadalia to the Hamachi client, that will encrypt all communication between the group secure VPN provided by Hamachi. There's also a few more configurations that come between all this on the client side for Hamachi but that's the jist of it. I'd produce a tutorial if enough people request it, hope that answers your question to a fool proof secure chat method.
