A node as an editable block

I want to create a edit node into a block with ajax submit.

I wanted to try panels 2 minipanel with a node%/edit override together. But some hour later ... nothing found yet.

This raw view may be handy: http://drupal.org/node/48816

But why not using some php? Below is a raw version

global $user;

$sql = "select nid from {node} where uid == %d";
$result = db_query( db_rewrite_sql( $sql), $user->uid);
$row = db_fetch_array( $result);

if( isset( $row) && isset( $row['nid']){
$node = node_load( 30);
print drupal_get_form($node->type .'_node_form', $node);
