Addon communication between players

[arkemiffo]

Hello,

So, I have no idea how this would work if it does work, but is there some way for addons to communicate between players, lets say through a hidden chat channel or something?

What I mean is, if I build an addon that is meant to sync certain information within a group, guild, whatever, can that addon have a specified chat channel (not visible to the players) that it send information through so that the players can be synced somehow?

Thanks.
