The new Apple MacOSX "Tiger" server software announced yesterday in San Francisco showcases great convergence and integration of independent publishing (blogs-RSS) and real-time collaboration tools (multi-protocol instant messaging, text chat, and audio video conferencing). As a matter of fact "the iChat server will allow organizations or companies to deploy and run their own private and secure IM server. Apple has based the iChat server on the open source Jabber project, which uses SSL/TLS encryption to ensure privacy, and Kerboros for authorization. The iChat server works with both the iChat client in Mac OS X Tiger and most other popular open source clients available for Windows, Linux and even PDAs. Tiger Server's Weblog server, based on the popular open source project Blojsom, will provide users with calendar-based navigation, customizable themes, and work with Open Directory for user accounts and authentication. The server is also fully compatible with Safari RSS and enables posting entries using built-in web-based functionality or with weblog clients that support XML-RPC or the ATOM API."
