Are there any examples of non-trivial apps using this technology stack? We all saw the endless stream of rails blog apps back when that was cool, and now we're seeing the same thing with these todo and chat apps. I'd like to look at some code that has more warts on it.

That's a co-incidence, Developed a C# + Redis + Backbone.js TODO app last week myself! Demo running on Nginx/MONO :)

http://servicestack.net/Backbone.Todos/

Backbone.js + Redis == Elegance + Speed!

We like Backbone.js so much that the TODO app is the default on all ServiceStack's C# starter projects!

This is what I see being the next logical step for feature rich realtime webapps. Connecting the front and backends in a virtually seamless way with little to no real overhead.

Taking the Backbone.js Todos example and making the change to using your backbone-redis code is pretty slick. That and the chat example, they just work. My only wish is that the chat example's interface was a bit easier to use.

Keep up the great work, love seeing novel approaches to existing projects.

I put together the following in my "Tech to try" list. On the offchance that I'm not the only one here unfamiliar with these technologies, I paste a copy here:

* Backbone.js http://documentcloud.github.com/backbone/

  Backbone  supplies structure to JavaScript-heavy 
  applications by providing models with key-value binding 
  and custom events, collections with a rich API of 
  enumerable functions, views with declarative event 
  handling, and connects it all to your existing 
  application over a RESTful JSON interface.

* Node.js http://nodejs.org/

  Node's goal is to provide an easy way to build scalable 
  network programs. In the "hello world" web server example 
  above, many client connections can be handled 
  concurrently. Node tells the operating system (through 
  epoll, kqueue, /dev/poll, or select) that it should be 
  notified when a new connection is made, and then it goes 
  to sleep. If someone new connects, then it executes the 
  callback. Each connection is only a small heap 
  allocation. 

%%

* Redis http://redis.io/

  Redis is an open source, advanced key-value store. It is 
  often referred to as a data structure server since keys 
  can contain strings, hashes, lists, sets and sorted sets.

%%

* Socket.io http://socket.io/

  Socket.IO aims to make realtime apps possible in every 
  browser and mobile device, blurring the differences 
  between the different transport mechanisms. ... making 
  creating realtime apps that work everywhere a snap.

At watermelon express ( beta.watermelonexpress.com ) we have developed a webapp textbook which makes heavy use of this stack. It is a pretty heavy implementation of backbone ( in coffeescript, jashkenas i think we owe you a case of beer. ) I am in the process of weaving in redis pub/sub for our next iteration.
