Well I rewrote the contructor for RPC.php to:

function RPC()
{
    $this->server = xmlrpc_server_create();
    foreach ($GLOBALS['registry']->registry as $api => $app) {
		include_once $GLOBALS['registry']->getParam('fileroot', $app) .
'/lib/api.php';
    }
	if (isset($_services)){
		foreach($_services as $service => $args){
    		xmlrpc_server_register_method($this->server, "$api.$service",
array('RPC', '_dispatcher'));
    	}
    }
}

I also changed the _dispatcher method in RPC.php to read:

function _dispatcher($method, $params, $data)
{
    $method = str_replace('.', '/', $method);
    if (!$GLOBALS['registry']->hasMethod($method)) {
        return sprintf(_("Method '%s' is not defined"), $method);
    }
    return $GLOBALS['registry']->call($method, $params);
}

Basiclly just switched from using "global $registry;" to use $GLOBALS,
but it did not change the next thing.

The call to hasMethod in the registry (using either $registry og
$GLOBALS['registry'])
returns false. So i started to debug that method.

I ended up totally confused. In the method "hasMethod" there is this check
if (!isset($this->_apiCache[$app]))
apiCache is not set, so the api.php file is included.
BUT after this, the $_services array is set, but has a count of (0).

All this is only when using XML_RPC, if I use $registry->callByPackage()
somewhere in my code
the "hasMethod"-method is also called, and here it behaves as expected.
(includes the file, and $_services has the right count).

Anyone has a clue here..??
Could it be that I commented out the authenticationpart of rpc.php ?
(for some reason it would not authenticate me, even though i know for sure
that the username and password can logon to horde(via imp), on the very same
installation that i call via RPC.

What I am doing is writing my own module for horde, and calling the RPC from
my own module.
I am doing this right now to test the RPC, I know that I could as well use
$registry->callByPackage().
