# WebRTC P2P communication (data, video and audio). Almost ready except for safari. # WebBluetooth Very experimental but some of the demo projects are really cool (control an AR drone quadcopter from a webpage).

Oh yeah, WebRTC! I forgot that one. I wrote a little multiplayer hovercraft racing game using WebRTC via peer.js last year. Super fun to explore programming networked systems in js.

  Is there any way to do this without a central server coordinating the peer connections? I'd love to host something off a static site but I've not figured anything out yet.

    You need something for the signaling part (sending the WebRTC offer, answer and ICE candidates to establish the connection). It's not necessarily a «central server», if you can convince you users to send each other the info text-encoded via Facebook or any messaging system, it will technically work (but it won't be really ergonomic for you users ;). I wonder if some people provide a SaaS solution for webRTC signaling. Quick survey: would you be willing to pay for it ?

      My specific thing was somebody asked for a demo of a heatmap, I knocked up a page that heat mapped the pointer and wanted every user to aggregate to the map. So no for such a demo I probably wouldn't be coughing up.

        For a demo you can just code a 20-lines signaling server using websocket with nodejs or anything.

WebRTC is realy cool, but does not work in Safari. Did cost us quite some time in a project.

> Almost ready except for safari. Unfortunately, that's not that simple. First of all, Edge doesn't implement the dataChannels, and FF and Chrome implements a slightly different version of the spec[1] (and neither implement the latest one) and things still break from time to time :(. [1]: fortunately, it's still compatible with each other, but the API as a few little differences that varies over time.
