Description
===========

This addons manages three communication channels ("guild","raid"if the player is in a raid and"sync"if the player is in a raid or party) and allows addons to use a RPC mechanism. Todays addons use one channel per addon, one for CTRA, one for each damage-meter, one for each guild/raid-managment addon, that can fill up the available chat-channel slots really fast, especially when you also join channels manualy. CommChannel only uses a channel if there is an addon that wants to use that channel and cleans the channel automatically when the last addon unregisters.



How it works
============

Whenever there is need to join/change the chat-channels, CommChannel generates a unique name for the"guild"and"raid"channel and joins them. For each channel, there is a list with all installed channel-modules, a channel-module is uniquely defined by a name. There usualy is one channel-module for each addon, but it's also possibly to register more than one channel-module from within an addon. Each channel-module also has to provide a interface. This interface contains functions that the module provides.
Upon recieving a RPC-request, each client looks up if it has installed the module, if yes, it looks up if the module interface provides the requested function, and if that's also true, it calls that function with the given arguments.

Messages which are sent to the communication channel are encoded in a very simple way so that each request can be parsed efficiently. The argument list is serialized from lua-objects, so it may contain strings, numbers, booleans and tables.

For more informations regarding the new API, please refer to the official addon homepage.
