backbone.js & JSON

Has anyone had experience using backbone.js with foulish? I've had to do the following to get JSON PUT requests to work.

Backbone.emulateJSON = true;

Because of this I had to change they way I grabbed JSON data on POSTS (was using php://input but now it's passed as a parameter). I'd like to support POST and PUT using php://input or have some helper method to consume the JSON submitted.

Of course I could just not understand how to do this w/flourish's current implementations. Or is there some PHP config that may be causing my issues?

Thoughts?
