Pub/sub pattern support?

Does IPFS support pub/sub architecture? If I subscribe to a file or blob of data, if any changes are made, a notice will be sent to my device that an update was made? So if I subscribed to a video channel on an IPFS youtube channel, when a new video is uploaded to that channel, my device would get a notice to fetch the content from either a central server or a neighboring device.

Yes pub/sub is planned. designs still TBD.
