That means - service is provided securely only via https protocol - and the other requirements are handled via corresponding web application (user management, access control, etc.) with full support of common browsers. What about http://owncloud.org/ ? It has "cloud" in the name but is an ordinary php web application with upload/download capabilities, user management, access control etc. so far as i known. -- LF
