You might have a look at node.js - I've heard recently of apps which combine node.js w/ redis pubsub to get a pretty nifty quick experience w/ no polling. From a scalability and performance point of view, this has a couple of drawbacks - susceptible to network latencies, quality (may be better suited for intranet), and second, each client may need it's own port (this for node.js).
Here's a pretty cool little app - http://www.web2media.net/laktek/2010/05/25/real-time-collaborative-editing-with-websockets-node-js-redis/ cheers, m On Mon, May 31, 2010 at 10:46 AM, Greg Ma <li...@ruby-forum.com> wrote: > Hi, > I am developping a little chat application with rails.
