Tracking Addon

I have a 2 box setup, i have my main computer directly in front of me and my alts computer directly to the right, the problem i have is that my alt is a miner and sometimes i miss mining nodes because i'm not watching his computer close enough. I was wondering if there is any addon out there or if it's even possible to create an addon that pinged the map or gave any kind of sound or signal that would bring my attention to his screen. Even an addon that could signal my main computer somehow.

Thanks
