Hi Bron! The work on the Braid HTTP extension also provides a "web push". We are also trying to find a general approach.

The current design allows clients to specify a "Subscribe" header in the GET request, which tells the server to keep the connection open and stream all updates to the resource, as they happen. We will be publishing a new draft within the next week or two.
