I like wordpress as a CMS and I think it's got a lot there with it's vast plugin library however the front end, dare I say it is a bit out of date.

I don't like the system of old going page-to-page and would prefer a single-page site powered by JSON/AJAX. I've used wordpress to make simple client sites but when it comes to anything more impressive, the system of templates which wordpress has is a bit lacking.

I'm used to using Backbone.js and Knockout.js for frameworks and require.js for module loading. I'm looking for a plugin or source reference for effectively removing the wordpress front end and using CRUD/REST and Javascript to build single page dynamic sites.

Can anyone point me in the right direction?
