[development] Passing a client value back to Drupal

I don't use CTools, but how I normally do this is define in the module a 
hook_menu item that is purely callback (i.e. 'type' => MENU_CALLBACK) 
and use that.  Tabular data I push using a jQuery $.ajax call and just 
serialize() the whole data HTML element.  To pass something back in the 
callback function (in module) just encode it using json_encode and in 
jQuery $.ajax call have a success handler that does something with it.
