New server module - JSON server!

http://drupal.org/project/json_server
Update: I am now writing about it!
The JSON server is a way to integrate services with JSON. You call a simple function, Drupal.service, to execute a service for you, in the following way:

Drupal.service('service.name',
  {api_key: "123461823762348756293", sessid: "sdfjahsldjfhlaksuertybsi", extra_parameter: "asdfasdf", other_parameter: ["nodes", "are", "good"]},
  function(status, data) {
    if(status == false) {
      alert("FATAL ERROR!!!!!");
    }
    else {
      alert(data);
    }
  }
);

This makes ajaxy things really easy to do. I could build a website that showed me a view with all nodes in it with a couple of calls, and it'd be pretty easy. It would go like this:

theSite = function() {
  Drupal.service('views.getView',
    {view_name: "front_page", fields: ["title", "nid"]},
    function(status, data) {
      if(status == false) {
        alert("Fatal error: could not load content");
      }
      else {
        $('.back').unbind('click');
        $('#content-area').html("<ul>");
        for(i in data) {
          $('#content-area').append("<li><a class=\"node-load\" href=\"#\" name=\""+ data[i].nid +"\">"+ data[i].title +"</a></li>");
        }
        $('#content-area').append("</ul>");
        $('node-load').click(function() {        
          Drupal.service('node.load',
            {nid: $(this).attr("name"), fields: ["title", "body"]},
            function(status, data) {
              if(status == false) {
                alert("Fatal error: could not load content");
              }
              else {
                $('.node-load').unbind('click');
                $('#content_area').html("<h1>"+ data.title +"</h1><br /><p>"+ data.body +"</p><br /><a href=\"back\">Back</a>");
                $('.back').bind('click', theSite);
              }
            }
          );
        });
      }
    }
  );
}
$(document).ready(theSite);

Note: completely untested. However, this shows the basics of the JSON server.
What this would do (in theory) is make a list of nodes, and when you click on the name of a node, it would load and the full node would be shown, along with a back button that would take you back to the view.
