Free for use.
Use just like regular Y.io, but the first parameter is the number of milliseconds to continually xhr-poll at. A new callback method/event has been added, 'modified', which will only be called when the server resource sends a 200 OK response.
The IO config object (third parameter to Y.io.poll) is just like, Y.io's config object; but a new on: { modified: function(txId, r, args){ /* your callback code here */ } } callback/event is added.
This will smartly poll the server using conditional GET requests (when method is set to GET).
