It would be nice to have an option in the Sites-Preferences to choose if the site should support Ruby on Rails or PHP. I successfully installed Phusion Passenger on my ISPConfig 3 but had to change the apache vhost-config manually (namely the BaseDirectory because RoR-Apps go into the root of the FTP, but the web hast to point to ./public/). After changing some preferences in the CP, ISPConfig overweites the config files and this breaks the RoR-App. Maybe I'll have a look into ISPConfig-skripts in order to tweak something for myself.
