Today I used this concept for an extension. It works fine.

plugin.tx_topsi = USER
plugin.tx_topsi {
	userFunc = tx_topsi_controllers_switch->main
	userFunc {
		list = USER_INT
		list {
			userFunc = tx_topsi_controllers_list->main

This is the switching controller. I have stolen 3 functions from pi_base to
 access a flexform field where I can select the controller to switch to.


require_once(t3lib_extMgm::extPath('topsi') .
'controllers/class.tx_topsi_controllers_list.php');
require_once(t3lib_extMgm::extPath('topsi') .
'controllers/class.tx_topsi_controllers_details.php');

	function main($content, $conf){
		$this->initPIflexForm();
		$key = $this->getFFvalue($this->cObj->data['pi_flexform'], 'controller',
'sGeneral');
		$return = $this->cObj->cObjGetSingle($conf['userFunc.'][$key],
$conf['userFunc.'][$key.'.']);
		return $return;
	}	
	
	/**

array.

		}
