Subject: Everything seems to work with the new Bu::ItoServer class, it
 operates very, very similarly to the Bu::Server class, except that every
 incoming connection gets it's own thread.  This functionality may have to be
 tuned later, to allow for maintaining a pool of connections as an option, but
 this is fine for now.

+	 * that a ServerSocket is one listening socket, nothing more.  Socket will
+	 * manage a pool of both ServerSockets and connected Sockets along with
+	 * their protocols and buffers.
+	 *
+	 * To start serving on a new port, use the addPort functions.  Each call to
+	 * addPort creates a new ServerSocket, starts it listening, and adds it to
+	 * the server pool.
+	 *
+	 * All of the real work is done by scan, which will wait for up
+	 * to the timeout set by setTimeout before returning if there is no data
+	 * pending.  scan should probably be called in some sort of tight
+	 * loop, possibly in it's own thread, or in the main control loop.
+	 *
+	 * In order to use a Server you must subclass it and implement the pure
+	 * virtual functions.  These allow you to receive notification of events
+	 * happening within the server itself, and actually makes it useful.
