About setting up several siteaccess. I think after the first installation, you need to create another teamroom node, then you will need to create a new siteaccess manually, just copying the site01 siteaccess folder, and renaming to site02, then changing site.ini.append.php and content.ini.append.php settings, only the settings about the root node id and default page. Finally will you set settings/override/site.ini.append.php and include the new siteaccess.
