Magt is a msn daemon that acts as a agent/proxy to all msn connections in a network.
It achieves that by having the firewall to redirect all outgoing connections to port 1863(msnp) to the daemon.
It then hijacks the tcp connection and starts to apply policy to the same.
With this arrangement it's possible to filter the entire protocol, and that's what we expect to do in the future.
By now (v0.0.1) you can prevent users and/or domains from connecting to msn and log the entire conversations they have.
