""" This is an example of using the server to server implementation to do a
basic chat style thing. It accepts commands from stdin and outputs to stdout.
It assumes that ucids are of the form <user>@<domain>, and uses <domain> as
the address of the remote home server to hit.
Usage:
python test_messaging.py <port>
Currently assumes the local address is localhost:<port>
