Is there a way to hook into the global or 'per-job' event stream?

One approach could be to allow the user to submit a listener on the event
stream, which presumably contains all the relevant information about
availability and location of  result partitions (and other stuff of
interest). Writing a little service to send that info down to a client is
pretty easy from there.
