what is Orbited?

from my understanding obited can do b开发者_StackOverflowoth comet and xmpp ? it is better than using typical comet library dwr right?

Orbited is a library to create 'realtime' applications that run in a web browser (it implements a technique known as Comet). More specifically is provides code and strategies to implement many protocols (xmpp, irc, stomp, amqp, etc) on top of what is known as a "web socket" - an object that abstracts away the many peculiarities of actually implementing Comet. Furthermore, Orbited describes, and in some cases provides, the back-end components (asynchronous webservers) that need to know and work with the front-end Comet clients.

Here is a little more detail on Comet and how Orbited plays in:

What makes Comet more complex to implement (than making an Ajax app, say), is that you need both the client (a Comet javascript client) and the server (an asynchronous webserver like Twisted) working in conjunction, and this is what you get with Orbited - both the javascript client and the server.
