Sessionless Networks
So far, the network connections you've seen in this topic have mostly
been dedicated connections between two objects. Serial communica-
tions involve the control of a serial port; mail, web, and telnet connections
involve a network port. In all these cases, there's a device that makes the
port available (generally a server), and something that requests access to
the port (a client). Project 8, Networked Pong, in Chapter 5 was a classic
example of this—in that application, the server handled all the commu-
nications between the other devices. In this chapter, you'll learn how to
make multiple devices on a network talk to each other directly,
or talk to all the other devices at once.

The shoes exchange messages with a multimedia computer via XBee radio. When you moonwalk in the shoes, your
pace and rhythm controls the playback of music from the computer.
