here is a class I made for msession it may give you some pointers :)

<?php
class msession_class{
        var $ses;                                               //session on flag

        var $message;                           //error message holder
        var $modulename;                //type of module, should be user
        var $sessionid;                 //
        var $sessionlife;               //how long inactive before the session should 
time out
        var $host;                                      //client host

                endif;
        }
}
?>

usage
<?
include_once('msession_class.inc');
$ms = new msession_class('TESTSESSION');
..thats it

if you want to force it to use the same session from another server/domain with
session_id set to the session you want start like this:

include_once('msession_class.inc');
$sessionid = '';
if(isset($_REQUEST['session_id'])){
        $sessionid = $_REQUEST['session_id'];
}
$ms = new msession_class('TESTSESSION','','',$sessionid);
