SomewhatSecureChat - Chat with another computer on your network!

This free, simple chat application that will allow you to securely chat with another computer on your LAN (on your local network, though it could work over the internet but not without some changes to account for NAT - like port fowarding).  It was written in VB .NET, so you'll need the .NET framework installed in order to use it.  Click here to download it.

Both parties will need to have this application running (and listening) in order to chat.   Simply agree on a mutual password and record your friend's listening port number and IP address, and you'll be chatting in no time!  Somewhat Secure Chat is only for Windows.  This easy to use application is free and open-source; feel free to improve and distribute this program!
