Long polling/push events between rails and ruby client

I search for a suitable way to build a pub/sub service between a Rails app and multiple Ruby clients.

I tried faye and faye-rails so far, but they are are not suitable, as messages getting queued up and not delivered until the client which is listening to the certain channel is restarted. Also I am not able to use a service like Pusher or PubNub.

Any recommendations?

Cheers Martin

For Rails 4 you may take a look at ActionController::Live. Won't that be suitable for your needs?

class MyController < ActionController::Base
  include ActionController::Live

  def stream
    response.headers['Content-Type'] = 'text/event-stream'
    100.times {
      response.stream.write "hello world\n"
      sleep 1
    }
  rescue IOError
    # client disconneted
  ensure
    response.stream.close
  end
end

For earlier Rails you may give a try to this approach: Ruby on Rails 3: Streaming data through Rails to client, Rails 3.2 streaming (the 2nd link is to notice the Last-Modified header)
