1) The display updates live when requests are received.
2) Supports PubSubHubbub. For example you can pass an inbox target URL in the subscription request to an RSS/Atom feed hub, and feed updates will land in the inbox.
3) Fancier API. Mainly this is the realtime stuff, which makes it possible to write your own JavaScript client that reacts to HTTP callbacks.
