Good points, Brian. I'll note that RESTCONF has built in websocket support for notifications of data changes through the streams API [1]. Thus, you can subscribe to data change events from an external web socket client. This might be a useful start placing if you would prefer to leverage existing ODL infrastructure instead of writing your own DTCL, which might be a daunting way to start :). Hope this helps!
