How to load $field_myfield_rendered for node not currently being viewed?

Hi all.

I'm using a variable to load CCK values from another node using the following code:

  $node = node_load($nid); 
  print $node->field_my_field[0]['value'];

However, one of the really nice features of CCK is, if you're viewing a node with CCK values set, you can print a rendered version of the value or group using print $field_my_field_rendered; OR print $group_my_group_rendered;

But I want to access these variables from a different node (and different node type) to save myself quite a bit of code and maintenance. Note also that the fields are of type node reference.

Can someone point me in the right direction?

Thanks,

Dan
