forbi is a TCP-based communication utility with PKCS#1 OAEP RSA encryption. It consists of a server and a client. The server keeps track of online users and forwards messages from clients to other clients. It is easy to configure what the forbi client should do when it receives a message. Its default action is to show it in a small window.
forbi is designed to be both a secure message sender and a "pre-chat" message mechanism. If you want one of your friends to join an IRC channel, for example, you simply send him a message:
forbi-send 'Mr. Spock' 'Come to #thechannel now!'
(Note that this will only work if both you and your friend have forbi clients running.)
Because your friend has his forbi client configured in a way that works best for him (perhaps he has configured his client to run a program that makes a lot of noise when he receives a message, or maybe something else), he is sure to notice your message.
Just run this (requires that you have python-setuptools installed):
Get the newest version of forbi at http://metanohi.org/projects/forbi/ or at http://pypi.python.org/pypi/forbi
Extract the downloaded file and run this in a terminal:
python setup.py install
To see a list of forbi's command-line options, run forbi --help.
As a client
The forbi client can only be used together with a forbi server. If you don't know of anyone with a forbi server, you can run the server on the same computer as your client. In this case, the host address you must give the forbi client is localhost.
The client will run just fine with no command-line arguments. To start it, just run forbi. When it is up and running, you can send commands to it with forbi-send. To see what commands exist and what arguments they require, run forbi-send --help.
See the examples/ directory for simple message receival scripts.
As a server
It is equally easy to run forbi as a server. The simplest way is to run forbi -s. Be aware that while data transportation in forbi is secure, protection against overflooding is non-existent. Anyone can register as a user on a forbi server, and there are no limits (except for those imposed by the underlying system) on how many clients can be connected to the server at the same time.
forbi works by sending commands back and forth between server and clients. These commands are not at all frozen and could very well change in any eventual new releases. There are no detailed descriptions of how the responses to commands should be, but it works for now.
forbi supports adjusting settings using a config file. To see an example of such a config file, take a look at forbi.conf in the examples/ directory of this distribution.

forbi is written in Python and uses Git for branches. To get the latest branch, get it from gitorious.org like this:
git clone git://gitorious.org/forbi/forbi.git
