Isotoxin is a feature-rich secure messenger that lets you connect over your local network or the Internet. The program supports audio and video, desktop sharing (view only), file/folder sharing, inline images, group chats and user profiles. Available extras include spell check, avatars, themes, auto gain / noise filter for audio and much more.

The Tox protocol is peer-to-peer, meaning no central server is necessary for the network to function.

Includes basic support for the XMPP (Jabber) protocol.

@Realist - Just go to Their "app" is just a wrapper for that.

@Realist: I haven't tested it because, unlike Isotoxin, WhatsApp is only out for Win8 and higher, closed source, and and is owned by Facebook. Their Wikipedia page lists some other concerns.
