Ales: does <demand targetState="Instantiated">WebServer</demand> mean 
"install me once WebServer is instantiated but before it reaches the 
next state"? Or is it "install me once WebServer is at least 
instantiated (although WebServer could be at a later state)"

The former could only be reliable if the MC knew about ModClusterLoader 
before it started handling WebServer.
