open_basedir + Mass Virtualhost

Hi, i read an old link about possibility to use open_basedir in a massive virtualhost apache/apache2 with a patch made by Jason Greene. This is link: http://marc.theaimsgroup.com/?l=php-dev&m=97145490702792&w=2 Here there is another one more about this patch one year after: http://www.phpbuilder.com/lists/php-developer-list/2001042/0075.php I would like just to know if an updated patch exists or if anyone of you knows more ways to let open_basedir work with mass virtualhost. Regards Thx & Byez DoM
