I got a disconnection message after a few seconds and had to reconnect, but i'ts a cool demo.<p>I started building (and am still working on) something similar in spirit back in August: a real-time collaborative game-making tool (<a href="http://craftstud.io/" rel="nofollow">http://craftstud.io/</a>). I started it as a Web app using SocketStream but I ended up switching to a downloadable native app for multiple reasons:<p>- building a complex Web-based app UI is daunting and the result is often slow or doesn't feel very native. I hope the upcoming Web Components / Shadow DOM specs will help fix this (<a href="http://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html" rel="nofollow">http://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow...</a>). Basically they will allow proper widget encapulsation.<p>- WebSockets force a centralized approach (costs go up) and are TCP-based which make them jerky for a lot of real-time use cases. (WebRTC will probably fix some of this too)<p>I described in more details why & how I switched in this post: <a href="http://forums.tigsource.com/index.php?topic=22939.msg652055#msg652055" rel="nofollow">http://forums.tigsource.com/index.php?topic=22939.msg652055#...</a>
