In some use cases this might be useful.
In our case we are working with Windows VMWare slaves that need to run as admin, there is no way to do this with ssh and DCOM doesn't work at all. I want to let the VMWare plugin create a slave with an empty master commando, so it comes on offline. The VMWare plugins then powers on a slave that starts the swarm client elavated through a scheduled task.
Convoluted, yes, but this feature might also be useful for other people perhaps in simpler cases.
