I think it's too complicated, already: In my simple world nodes with status "green" are OK to run any resource, nodes with status "yellow" should not start new resources, and nodes with status "red" should move away running resources. Ok, I see the some people have a desire for "orange", "indian yellow" and a lots of different colors on the spectrum, but thinking of the seemingly endless cases to test, I prefer a simple world ;-)
