- * The sending application doesn't necessarily know what particular applications

- * the messaging system has different Message Channels for different types of
- * information the applications want to communicate. When an application sends
- * information, it doesn't randomly add the information to any channel available;
- * it adds it to a channel whose specific purpose is to communicate that sort of
- * information. Likewise, an application that wants to receive particular information
- * doesn't pull info off some random channel; it selects what channel to get information
- * from based on what type of information it wants.
