 ;; Cross-layer relaying between adjacent dataspaces
 ;; TODO: protocol for *clean* shutdown of a dataspace
 
+;; TODO: Actually elide the need for relays entirely, by allowing an
+;; actor to manifest in multiple dataspaces (multiple
+;; points-of-attachment), and by placing assertions and subscriptions
+;; directly in the dataspace concerned. (Done naively, this would
+;; avoid manifesting observed assertions in intermediate nested
+;; dataspaces; but then, if anyone cared, they'd be observing the
+;; tuples themselves - right?? Oh, maybe observing the observers would
+;; be an, er, observable difference.)
