ipc.log will accept any number of arguments and if ``ipc.config.silent`` is not set, it will concat them all with a sincle space ' ' between them and then log them to the console. This is fast because it prevents any concation from happening if the ipc is set to silent. That way if you leave your logging in place it should not effect performance.

The client connects to the servers socket for Inter Process Communication. The socket will recieve events emitted to it specifically as well as events which are broadcast out on the socket by the server. This is the most basic example which will work for both local Unix Sockets and local or remote network TCP Sockets.

#### Server & Client for UDP Sockets
UDP Sockets are different than Unix & TCP Sockets because they must be bound to a unique port on their machine to recieve messages. For example, A TCP or Unix Socket client could just connect to a seperate TCP or Unix Socket sever. That client could then exchange, both send and recive, data on the servers port or location. UDP Sockets can not do this. They must bind to a port to recieve or send data.
This means a UDP Client and Server are the same thing because inorder to recieve data, a UDP Socket must have its own port to recieve data on, and only one process can use this port at a time. It also means that inorder to ``emit`` or ``broadcast`` data the UDP server will need to know the host and port of the Socket it intends to broadcast the data to.
