This plasmoid shows if other computers on the network are up and running or not. A sleeping computer on the same lan can be turned on by wake-on-lan.
The status is evaluated on basis of ping, which is executed every 5 secs. Currently this value is not configurable.
The plasmoid requires the icmp dataengine to work.
This is a fork of Kood Morning http://kde-look.org/content/show.php/Kood+Morning?content=117378. It was necessary to fork after two years of no development of the original work. I hope it can resume one day, so the code can be merged.
