Rails 4 will let you stream the update to the page, but in Rails < 4, you want to have the page poll for changes. Use Prototype's Ajax.PeriodicalUpdater or whatever the jQuery equivalent is. Prototype's can be configured to throttle back the frequency of requests after a period of same-results answers, and of course you can remove the behavior once the update has been delivered.
