Here's a little code snippet to show what I had in mind.

A recipe registers itself in some way:

if (file_exists("$FarmD/cookbook/pmwikiautoupdate.php")){
     include_once("$FarmD/cookbook/pmwikiautoupdate.php");
     PmWikiAutoUpdateRegisterReceipe("myrecipe", "2.0", 'http:// 
somehost/');
}

The "source" should provide a version information:

     PmWikiAutoUpdateRegisterReceipe("myrecipe", "2.0", 'http:// 
somehost/', true);

The script:

<?php
Markup('pmwikiautoupdate', '<split', "/\\(:pmwikiautoupdate:\\)/e",  
"PmWikiAutoUpdateList()");
function PmWikiAutoUpdateList(){
     global $PmWikiAutoUpdate;
     $recipes = $PmWikiAutoUpdate['recipes'];

     $out[] = "|| border=1";
     $out[] = "||!Recipe||!Intalled Version||!Source||!New Version  
Available||";
     foreach ($recipes as $recipe) {
         $data = "";
         $fp = fopen ($PmWikiAutoUpdate[$recipe]['url']."? 
action=pmwikiautoupdate&rname=$recipe", "r");
         while (!feof($fp))
         	$data .= fgets($fp, 256);
         fclose($fp);
         if (!$data) continue;
         $xml_parser = xml_parser_create();
         xml_parse_into_struct($xml_parser, $data, $values, $index);
         xml_parser_free($xml_parser);
         $version = trim($values[$index['VERSION'][0]]['value']);
         if ($PmWikiAutoUpdate[$recipe]['version'] != $version)
             $out[] = "||".$recipe."||".$PmWikiAutoUpdate[$recipe] 
['version']."||".$PmWikiAutoUpdate[$recipe]['url']."||$version||";
     }
     return implode("\n", $out);
}

function PmWikiAutoUpdateRegisterReceipe($rname, $rversion, $rurl,  
$rsource = false) {
     global $PmWikiAutoUpdate;
     $PmWikiAutoUpdate['recipes'][] = $rname;
     $PmWikiAutoUpdate[$rname]['version'] = $rversion;
     $PmWikiAutoUpdate[$rname]['url'] = $rurl;
     $PmWikiAutoUpdate[$rname]['source'] = $rsource;
}

$HandleActions['pmwikiautoupdate'] = 'HandlePmWikiAutoUpdate';

function HandlePmWikiAutoUpdate($pagename) {
     global $PmWikiAutoUpdate;
     $rname = $_GET['rname'];
     if ($PmWikiAutoUpdate[$rname]['source'] == true){
         header ('Content-type: text/xml; charset="UTF-8"');
         echo "<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
         <pmwikiautoupdate>
              <name>
                 $rname
             </name>
             <version>
                 {$PmWikiAutoUpdate[$rname]['version']}
             </version>
             <url>
                 {$PmWikiAutoUpdate[$rname]['url']}
             </url>
         </pmwikiautoupdate>
         ";
     }
}
?>

I believe I read in the mailing list about page vars set on a page  
itself with something like "parameter:value". But I can't find the  
thread at the moment. So we possibly could also subscribe to a  
particular update page with "version:x.y" on it.
