@jkarneges awesome! So in theory let say I have a push notification thing that sends messages to a web client / mobile app without any restriction (i.e. fully Public channels) I can do that by serving a fairly static php/ruby/whatever page with the proper Grip headers. Clients connect to that pushpin endpoint and hang to the connection. Meanwhile from a side channel I submit messages to pushpin using REST or the libraries and those messages get delivered for whoever is listening to the channel at that stage and discarded when the broadcast is done?
