However, you suggested that it's possible to do so if we provide dedicated php-fcgi process for each UID. How exactly do we do that?

Just define a dedicate PHP FCGI or LSAPI application, php script handler, and set "CGI Chroot Mode" to "Doc Root UID".

For multiple similar vhost, you can use our vhost template feature.
