I put together a preliminary version of the above in a couple days a while back. There are a couple of bugs to shake out, and I'll want to battle test it, probably as part of the UI for ocap-merkledag. But once I've gained some confidence I have interest in possibly using this as part of Sandstorm core, as I think it will make the UI code much easier to work on & maintain.
