unMessage is an anonymous messenger that uses Tor to hide metadata of participants. Its still in early development, however a major new feature such as Tor-to-Tor audio chat (the first such implementation we are aware of) has been included. Major additions like file-sharing support, video conferencing and a portable code-base for mobile platforms are planned.
Their major goal is to provide a better UX and a competitive feature set to move users away from proprietary solutions that don't respect privacy. Its not ready for mass adoption yet, so only the more technical audience among you should go ahead try it out. Feedback and/or pull requests are highly appreciated.
