Ok, this is different...a web 2.0 cms with blogging, wiki, tagging and the standard set of things too..

Pachyderm 2.0 is currently in release as a server-hosted, browser-based authoring platform running on servers provided by the New Media Consortium to its membership. The server versions of Pachyderm 2.0, which are being built for Windows, Linux, and OS X servers, will be freely available for download from SourceForge in the first quarter of 2006 when Pachyderm is released in open-source. The availability of the server package downloads will be announced broadly at that time.
