Freenet is an application providing secure and extremely censorship-resistant network for static data and chat.
In Debian, Freenet can be used as external application; It is written in Java, so it should be quite secure to use especially when running this server as separate user (adduser srv_fn --disabled-password).
There exists FMS_application boards/chat program for it, on Debian Wheezy it requires fixed libpoco to work properly described there.
