OK, add_post_meta is the answer, and I've hacked the following
together in xmlrpc.php, in mw_newPost()...

    $meta = $content_struct['meta'];
    if (is_array($meta)) {
      foreach($meta as $key=>$val){
        add_post_meta($post_ID, $key, $val, false);

This is doing the trick for me. I suppose the mw_editPost function
should be edited also for completeness, to allow the post meta to be

This approach also seems to be acceptable, according to the metaWeblog
API (http://www.xmlrpc.com/metaWeblogApi), i.e.

Where an element has attributes, for example, enclosure, pass a struct
with sub-elements whose names match the names of the attributes
according to the RSS 2.0 spec, url, length and type.

Any chances of getting this change into trunk?

Many thanks,
