You are able to add additional preprocess functions as per
http://drupal.org/node/223430

For example... here is a function you can insert into the theme's template.php file:

function THEME_preprocess_node_to_json(&$variables){
$items = '';

$node = node_load($variables['nid']);
$node = (object)$node;

if ($node->field_project_date[0]['value'] != null && $node->field_project_date[0]['value'] != ""){
$raw_date = explode("-",$node->field_project_date[0]['value']);
$variables['date_completed'] = date('F', mktime(0,0,0,$raw_date[1],1)) . ", " . $raw_date[0];
}

$taxonomy='';
if ($node->taxonomy != null){
$taxonomy = "<h1>Taxonomy</h1>";
foreach ($node->taxonomy as $cat){
if ($cat->vid == 3){
if ($taxonomy != ""){
$taxonomy .= ", ";
}
$taxonomy .= $cat->name;
}
}
}
$variables['taxonomy'] = $taxonomy;
