*
* The routines for sending/receiving Instant Messages.
*
+ * Note the term ICBM (Inter-Client Basic Message) which blankets
+ * all types of genericly routed through-server messages. Within
+ * the ICBM types (family 4), a channel is defined. Each channel
+ * represents a different type of message. Channel 1 is used for
+ * what would commonly be called an "instant message". Channel 2
+ * is used for negotiating "rendezvous". These transactions end in
+ * something more complex happening, such as a chat invitation, or
+ * a file transfer.
+ *
+ * In addition to the channel, every ICBM contains a cookie. For
+ * standard IMs, these are only used for error messages. However,
+ * the more complex rendezvous messages make suitably more complex
+ * use of this field.
