 ## Roadmap 🤷
 
-Adding multiuser support seems doable. Rather than actual users, this multi-tenancy will probably look more like namespaces in Kubernetes - a logical partitioning of resources created with a CLI.
+Basic multiuser support (multinamespace, actually) is now implemented. No node sharing or ACLs between namespaces yet though...
 
 Pre-auth keys should also be feasible.
