I doubt that idea is in scope at present Ivan, and maybe you'll have to invent your own mechanism. Maybe what you could do is create a 'Process Instruction' queue, and make your worker process check this queue regularly. Then another process could add an item to the queue that tells the worker process to do something, eg 'Stop working between 0200 and 0400'. Or, even simpler (but less secure), make the work process check a network folder for a file - inside the file is an instruction.
