What about websockets? This is very similar to subscription webhooks, but also different. Websockets have been gaining in popularity due to easy of use and implementation and low overhead. Plus, a typical server can hold open thousands of connections since many might just be waiting for an event to send/receive.

This. After doing my initial skim of the article, the first thing I noticed was they omitted sockets. I always thought sockets were the standard for streaming, real-time communication over the web and would at least be mentioned in a post like this.

Agreed. With current browser support (http://en.wikipedia.org/wiki/WebSocket#Browser_support) and fallback libraries (like http://socket.io/), I believe WebSockets are usually the best choice when it comes to real time communications.

Webhooks are great, although most "client" applications as commonly known (browsers, mobile) aren't able to act as servers in order to receive them.

One way around this problem is to route through some kind of bridge service. We've done this with http://webhookinbox.com/ which can receive webhook calls on behalf of clients.

Ah, at the title I thought this was going to be about WebRTC, something I'm pretty excited about, even though it has a quite a ways to mature yet (http://caniuse.com/rtcpeerconnection).

Interesting that they left out websockets. At this point Websockets seem to be reasonably mature, and with Socket.io/Primus/etc are dead easy to use, and allow for near-real-time 2 way communication. There do appear to be some scaling issues past a certain level with websockets though, a topic I haven't been able to find too much literature about.

As for webhooks, are these more geared towards Server-to-server communication, like consuming an API on the back end? Is there any chance that in the future browsers will begin listening on our ports too?
