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.
