Just learned about this!
Can peers ->> master?
I want a system with a nexus with multiple nodes around the house. For example, a key-fob presented at S Door goes thru the hosting module/library returning a string of key data. Node wants to verify and authorize this key-in. Nexus has key#, status.... user, permissions... so if key is valid and user is active and permissions is set the door unlocks. I suppose I could have master poll frequently all peers, but this is ineffeicient.
