you could have the game reloadui whenever you go afk, and an external program edit the .lua files for your addon, and potentially read from the savedvars file if you wanted to communicate from inside the game to outside of the game.

If, say, every guild member had the same addon, the feed would always be as up to date as the most recent person to login or reload their UI.

EDIT:
also if you have defined a texture in your lua file, you can edit the texture and it updates on uireload: so you could also load the icons if you have a method of auto converting them to .tga
